I use Spotify. I have some Anker Soundcore iP30 ear buds that I got for $25 through Costco. They work well enough. I was thinking about getting an MP3/DAP and managing my own library though. Spotify's recommendations totally suck, but it's so easy to access. However, as of late, I feel that infinite options actually limits my listening, because instead of enjoying it, I'm always looking to what's next because it may be better.
