I also limited myself on Beatport purchases... I liked to go crazy with downloads but I felt if I bought a list of tracks I would always favor some and disregard the rest. I made it a thing to only buy 6 tracks at a time, that way I can truly sort out the ones I like most before purchasing, and actually take the small amount of time practicing and getting to know each track. It's nice to have a deep house folder with 75 songs that you will actually play and not have to waste time searching through hundreds of "filler tracks" that you never really had the intention of playing anyways.
