Music Discovery
Over the past couple of years, I've been using RateYourMusic.com for music discovery. Specifically, I've been working my way through the top 10,000 album list in reverse order and browsing through user-made lists.
Can RYM users be unbearably pretentious? Yes.
Is attempting to keep up with a top 10,000 album list that updates weekly a futile effort? Also, yes.
Commentary aside, for sheer variety and genre diversity, there is no beating RYM's breadth.
Github user dbeley made a couple of very helpful scripts to scrape data from the RYM site, which I've used to create an Apple Music playlist of the top-rated 10,000 songs.
