How many songs can a 8 megabytes hold?

80 MB is not a lot. Considering an average CD-R holds 700MB? in MP3 format an average CD-R would hold arounfd 150 average sized songs. So I'd be surprised if you got more than 15 songs in MP3 format. If the songs are in WAV format, which is the normal format of a CD then you are looking at a lot less than 15.
