ya how AS deals with different codecs and even masters can get annoying.
a very large part of my music collection is, ripped from LP's, into 24bit 96khz flac files, and i cant compete with those songs with people who use the CD version, since the mastering on the LP version isnt anywhere near as compressed and loud. Which is fucking amazing to listen too, and much better in my opinion, but gives me much less intense downhill sections in AS.
