Yep, it just did that. First strange part is doing some research this looks like the Adsense bot. This is a smallish amateur site that has nothing to do with Adsense. Also odd to see a bot grab an entire MP3, but my logs say that is what it did. I used to get paranoid by all the Googlebot activity my sites got, until I just realized that's the way Google is. I'll just assume this little critter got lost and ended up on my site. Still, odd.
