Actually, I’m gonna add another really simple option: Lyrion (Formerly Logitech Media Server). My wife swears by this one, supports local library, integrates with LastFM, and if you use Tidal, Qobuz, Deezer, or Spotify, you can integrate your streaming service with your local library for radio mixes.
Can install it right on a laptop or PC and connect to wherever your music is (local on the machine, on a NAS, etc.). After you install it, you can access it directly via a web browser or webapp, which will make it accessible from desktop or phone.
Props for the Hiromi recommendation, though I’d personally choose Seeker from the Alive album.
