Buy the music that you like performed by the artists you like the best and will listen to after you make your purchase. Don't buy something you will never listen to just because some on this forum suggests it. Listen to the samples before you buy. I suggest FLAC downloads.
Taking opinions from others will be a hit or miss proposition. Not everyone has the same setup and some systems will perform well and others may not be optimised for hi-resolution. Every component makes a difference. I have heard 'excellent' and 'good/fair' from the same download on two different systems. The system made more of a difference than the download. (just like two different turntables will have their own sound character playing the same LP) you may prefer one to the other and only your ears will make that decision.
