How many songs do the iPods hold from over 8GB to under 80GB?

Question

I already know how much the 8 and 80 hold, but what are the ones between them and how many songs do they hold? I cant find this anywhere

Answer 1

10 GB = about 2,000 songs
20 GB = about 4,000 songs
30 GB = about 7,500 songs (what I have)
40 GB = about 8,000 songs
60 GB = about 15,000 songs

Also there's the 160 GB Classic, which holds about 40,000 songs. Crazy, huh? =)
