I'm in university now, so most of my music discovery is going to live shows and talking with my friends, but I used to be really into using the internet to find my music. My first stop was always either r/futurebeats or r/indiewok, but the turnover rate (especially with r/indiewok) wasn't fast enough for me. I started following youtube channels that showcased the type of music I liked: majestic casual and versimilitude mostly. Once I had a good list of artists I liked, I would visit their record labels' sites to check for new music from other producers on the label. For me this was mostly: Alpha Pup, Ghostly, and Ninja Tune, as well as wedidit. I also started following producer blogs like ISO50 a.k.a Tycho for further music discovery, as well as blogs about the genre like The Purple Bay. It's really about jumping from link to link that you find on websites.
