I am a musician, an audiophile, and have a crazy-big collection (30,000 + tracks). The music is always on in my life. I am tied in with Pandora and many streaming apps, radio, and what's new and trending, to classical.
So here's what I use: iTunes. Really.
I've been full circle on other players a few times, and return to iTunes.
I also use iTunes to encode from CDs, at no less than 192 Kbps MP3 .
