I subscribed to the.Apple Music trial today. I found I can use the web-browser interface to listen to music at work, so I’m giving it a go for work music. But while I’m reasonably tech savvy generally and Apple products specifically, I know almost nothing about Apple Music. I need help. 
Thanks!
- Do I let it merge my music into Apple Music on my desktop? If I cancel the subscription later, am I at risk of losing music? (I remember Apple Music deleting people’s libraries five years ago when it launched)
- Does Music learn from me “Love”-ing songs or albums? If I take time to do that, will it get better at recommending playlists?
- How do I sync or stream from my Watch?
- Any must-know tips and tricks?
Thanks!
