Nope, it's random. The original meme just had you list the songs, but I thought it'd be cooler with some lyrics. You might want to skip instrumentals, although I didn't. Also, my original post is at lj and I linked to youtube videos over there, just in case someone wanted to actually hear the songs - you could do that too, if you wanted! (...I'm on vacation.)

(Ha! That is an excellent icon.)
