Personally, I often use YouTube to discover music, or hear songs in tv/movies and very occasionally Ill have the radio on. Not often these days though!
For long term listening, iTunes is my primary go to, and I mean paid for songs, not Apple Music. Having musicians in my family I made the decision to buy all my music legitimately once I had a source of income and was able to. I also like being able to open my music in other software and I believe only the paid for DRM-free iThnes music can do that.
As for kind, its kinda all over the place. The majority is synth heavy stuff, with a fair amount of pop and metal mixed in, plus a generous dollop of country. There are some genres that I just dont connect with as much, like rap, but even then I have a few rap songs that I love.
