Think you've heard all the songs on They Might Be Giants' Here Comes Science (review)? Well, you probably haven't, as Amazon now has the album up in mp3 format (iTunes previously had an exclusive). It includes an Amazon-exclusive track called "Waves." Assuming that you already have the album, is the track worth your 99 cents? Clocking in at just over a minute and a half, it's not an instant classic, not like "Meet the Elements" or "I Am a Paleontologist," and has a B-side feel. But it's not without merit. It's electronic in sound, a little bit like "Am I Awake?" off Indestructible Object, and it's one of the most straightforward lesson songs from the new album, conveying how sound and light and water move in waves. It's not essential for the casual listener, but if you're a fan (or have a science unit on light or sound coming up), it's worth the 99 cents. (Thanks to This Might Be A Wiki for the heads up on its availability.)
