ive heard a lot of those 320 kbps from various sources and decided i wont ever spend a cent on mp3/ogg etc . none of the files sounded better than the 192s i made myself. if it's wav / cd-r sure ,ok. but those "commercial mps3" are still sort of a joke. often hammered with some funny loudness maximizing limiters the traks lose at least 50% of its dynamics. (often turning into a "punk-rock remix" of a techno trak)
honestly i'd rather get an "illegal" file and send 5 $ directly to the artist. sad thing is - 95% of stuff i got this year is by ..drexciya ;/ /12
