Not all T3 sources are bad. But if you're aiming for the most recent popular music then one should be a little wary of T3 sources. Downlding from multiple sources of cable & modem can still be very fast anyway. That's something else. Some people don't check their downlded files immediately & may leave them in their share folders for weeks before realising they downlded a bad file. So that gets back to checking bitrate v's file-size.
