Well, i was at Juno Download tracking some names of old school jungle ( im big fan of early bass music) and found ambient, drone, experimental and industrial categories . I always thought its was an only dance floor oriented music store ( ie at Beatport there isn't ambient) but i was wrong. Everything its perfectly organized, by genres, artists, labels , bpm (lol at beatless music) , dates, best selllers, bad sellers, and so and so ,of course there are also previews You can buy at 192KB/S MP3, 320KB/S MP3 , WAV , FLAC , ALAC, AIFF formats also whole albums or single tracks. All prices are in english pounds.
