I was wondering about those of you who download music from the internet...

When you download using mp3 format, the kbps usually is around 320 kbps, but with wma it is usually around 192kbps...yet they sound almost exactly the same with no discernible difference in quality, but i have heard that the higher the bit rate the better the quality overall...for example, WMA has a higher one called "Lossless" which is supposed to be a perfect digital copy and it is about 900 or so kbps...anyone know if the higher bit rate is better quality?
