If you're trying to get 100 soungs on a CD, unless you're in some crazy thrash band there's really only one solution. If you're willing to play it only on your computer through Winamp, you can burn a CD of MP3's. My friend put 8 of his CDs on one disk this way. You can invest in a CD player that plays MP3s too if you want to. I know my DVD player does it, and they make walkmans that will do it. If this isn't what you wanted to know, sorry.
