Nope..  You are wrong..  MP3 uses compression..   1 tenth of 10 megs per minute
is 1 meg per minute..  thats 128kbps..  An equal to CD quality MP3 is 128kbps,
anyone who downloads anymore than that is wasting space, thus eliminating the
need for MP3 compression..  The whole point of having MP3's is the same quality
in 1 tenth the space.

1411kbps at 10 megs per minute divided by 10 (1 tenth compression) = 141.1 
after you factor in the compression loss, you get approx 128, WHICH IS CD
QUALITY!!!!!
