The Apple Music three month trial had a positive affect on my listening habits. I tried it, hoping to discover new music. But the UX was a slog. No easy pivot points on artists and songs. A DJ workflow vs listener workflow, which added complexity. No collaborative filtering.
So, I switched to Spotify. The "Discover Weekly" section that uses Echonest (I think) has surfaced new artists and songs to explore. Pivot points on songs, artists, and playlists are straightforward.
Have spent 100s of hours hours ripping and curating high 100s of CDs over the last 25 years. Barely touch em. At this point, if you'd ask me to choose between my old catalog and Spotify, I would choose the later. Heh, thanks to the Apple Music 3 month trial.
