Try to stay away from dwnlding from T3 sources. Most corrupt files seem to originated from those sources! Also before choosing to dwnld, make a note of the file's bitrate & size. I've noticed that sometimes the T3 mp3's will show different bitrates but same size which doesn't make sense! The larger the bitrate, the larger the file should be. But you'll have greater chances of not getting corrupt files if you choose modem, cable/dsl, or T1. Sure modem are a bit slower but there's many more of them & they're reliable files in general.
