i use youtube, it has more music than soundcloud, beatport, spotify, etc.. I could explore it 24/7 and never hear it all, and i have a discogs window open to to research
lol I've been using YT for music for years. it's maybe slightly cumbersome, and a total waste of bandwidth. but i think its the largest catalogue of music available. i only recently stopped using it quite as much once they neutered the search function (all you get is "recommended for you" etc). but i'm happy to see a fellow youtube listener, thought I was the crazy one in my friend group
