I have a 1 terrabyte of hard drive space free, and not even I mess with flacs, haha. They are simply too big.. 30 megabytes for a 4-5 minute song... times 89,000 songs or so.. there goes my entire 1 TB of space
Yeah they do sound the best, but still, the human ear cant tell the diff between 192 kpbs and 320 kpbs unless the music is being played on a huuuuge sound system. theres a lot of audiophile elitists that will disagree with that but the research clearly backs that up.
I got FLAC's for my favorite groups though.
