Well, they are usually 80 mins, right?

In that case, if you divide 700mb by 80mins it equals 8.75mb/min which is 146kb/s (rounded up). I really thought it was alot higher than that.... But I never really tried to figure it out.

I think we're getting kiloBytes (kB) and kilobits (kb) mixed up here.

I think we're getting kiloBytes (kB) and kilobits (kb) mixed up here.maybe.... And I think I converted slightly wrong too.

149.33 KB/s (kilobytes)
1194.67 kbps (kilobits)

Thats if a kilobyte is 1024 bytes

Now, my other calculations are right if 1 kilobyt=1000 bytes

146 KB/s (kilobytes)
1166.67 kbps (kilobits)


Now I was confusing kbps with KB/s. The music I have is kbps, not KB/s. So those numbers make alot more sense.
