I was listening to one of my favorite new albums, Ray Guns Are Not Just the Future by The Bird and the Bee. In particular, I was listening to the song “Witch,” a song that is extremely evocative of the music of classic James Bond movies (and not just because I’ve been watching Moonraker on my iPhone over the past couple of nights). So I decided to google “The Bird and the Bee” Witch “James Bond” to see if anyone had discussed this correlation.

The first result back was the Rolling Stone review of the album, which I was disappointed to see had only received a 2-star rating. The review is scornfully dismissive of the blatant influence of Burt Bacharach, bossa nova and the Bee Gees. So imagine my surprise when I read Rolling Stone’s 3-and-a-half-star review of their first album, which mentioned, in a far more appreciative tone, the blatant influence of Burt Bacharach, bossa nova and the Beach Boys.

Granted, the Beach Boys are probably a more enduringly worthy influence than the Bee Gees. But I happen to really like “How Deep Is Your Love” (which The Bird and the Bee covered on an EP a couple years ago and which, I have read, but I hasten to note I would not know from personal experience, was also included in the Sex and the City movie soundtrack), and I doubt that the influence of the Beach Boys vs. the influence of the Bee Gees would, on its own, make a star-and-a-half difference in the quality of the two albums.

I have not actually heard The Bird and the Bee’s first album (yet), but if their second is only a 2-star effort, then the first must be a 3-and-a-half-star masterpiece beyond anything in the known world of music.

The real problem here is that musical tastes are highly subjective, even among music reviewers who work for the same publication. But although the reviewers in Rolling Stone get a byline, RS still presents a monolithic face as the voice of popular music criticism, and as such it would be nice if they could maintain a little continuity in their treatment of individual artists from one album to the next, at least to the extent that the star ratings should not be applied as subjectively as the commentary within the reviews themselves… or, the star ratings should never be presented out of context without noting the name of the reviewer who assigned an album its rating.

For example:

As I’ve mentioned, I have taken a shine to Amazon MP3 as my primary source for music downloads now. Sorry, Apple. You know I love you, but Amazon’s just doing it better. Better selection, better prices, and usually better quality. Plus everything’s MP3, not AAC. And no DRM, ever.

And while I don’t anticipate ever switching media players (the iPod and iPhone have served me well, even if you’ve been stumbling a bit lately). My new car’s CD player supports MP3 (and, ugh, WMA) CDs, but not AAC. And yes, I keep an iPod nano in the car (note to potential thieves: no I don’t), but it’s still convenient to load up several albums’ worth of music onto a single CD and pop it in. No annoying cords or dangerous behind-the-wheel iPod fiddling.

So anyway… yeah, Amazon MP3. And MP3s in general.

I’ve ripped my entire CD collection multiple times. First, back in 2001 or so, I ripped it all as 128 kbps MP3s. Then I got to the jazz CDs and noticed how bad 128 kbps actually sounded on some music. So I re-ripped the whole collection as 192 kbps MP3s. That was the smallest size where I didn’t really notice bad audio artifacts.

Then in 2004 Apple introduced the iTunes Store, and with it everything was 128 kbps AAC, Apple’s own, semi-proprietary format. Better compression-to-quality ratio, so 128 kbps AACs sounded as good (to me) as 192 kbps MP3s, at 2/3 the size. So I went back through and started ripping my CDs again, this time as 128 kbps AAC format.

Then last year Apple introduced iTunes Plus, with 256 kbps AAC format. Sure, they’re twice the size, but now I really can tell almost no difference between the compressed versions and uncompressed CD quality. So I started ripping again, but honestly I could not tell the difference between 256 kbps AAC and 160 kbps AAC, but I could tell the difference between 128 and 160. So 160 was my new standard. I only made it through about a quarter of my CDs at this new level though.

Then this year we had the release of my own music on some download sites, and I went with 256 kbps MP3 for those. Combine that with my new embrace of Amazon and their use of 256 kbps MP3 as well, and that pretty much sealed it. 256 kbps MP3 is my new format of choice, and I’m going through my entire CD collection and ripping it yet again in this format.

Which brings me to the whole point of this post. When you put a CD in your computer, iTunes (or whatever ripping software you’re using) grabs CD track information from CDDB. This data is submitted by users. Sometimes if you insert a new release or a really obscure album into your computer, it will tell you that track info could not be found, and it presents you with the opportunity to submit information you’ve entered. Which means any typos or other idiosyncrasies in your own personal way of entering this information will now become what anyone else who inserts the same CD into their computer will see, provided they’re lazy enough not to fix your dumbass mistakes. I’ve grown accustomed to fixing band names, correcting spelling, normalizing title cases (You Don’t Capitalize Articles, Conjunctions or Prepositions in Titles, but It Is Correct to Capitalize Pronouns and Verbs, Even If They’re Only Two Letters Long, Thank You Very Much), etc.

But something I’ve noticed from time to time, and never quite got, really bothers me. First off, I think the BPM field is pretty much useless. Unless you’re a DJ and you actually know the tempo of the songs you’re working with, you have absolutely no need for this field. But sometimes I see it filled in, and with the same value for every track on an album. Highly unlikely. It’s just finally dawned on me over the past few days why this is, though, and it’s because I’ve only ever seen two values in that field: 128 or 192. The same idiots who can’t spell also can’t tell the difference between BPM and kbps.

So, let’s have a little acronym lesson, shall we?

BPM (Beats Per Minute): The “tempo” or, if your musical knowledge is severely lacking, “speed” of a piece of music. How many beats (you know, the part of the music that helps you dance) there are in a minute.

kbps (kilobits per second): This is the amount of data in the compressed (MP3, AAC, WMA or whatever) file per second of music. In other words, it’s the compression quality of the audio file, quantified.

And now you know… the rest of the story.
