I listen to DJ sets on Soundcloud, then I'll try to Shazam any tracks I like (50% chance in my type of music, underground electronic) or ask in the comments for "ID Please?". Then I usually add it to my YouTube playlist [0] (Premium, of course), which gives recommendations, and I try to buy the record on Discogs if available on vinyl, which also has a recommendation engine.
