My whole family uses it. Saves me a bunch of money with 3 kids with different tastes in music. They always want the latest songs. I used to tell them no most of the time because I just couldn't justify it. I would buy about $20 a month between all of us though. The service costs me $16 and we can listen to whatever we want and on our own playlists. It's very worth it for me. It may not be for everyone though.
I moved over to Spotify after the free trial period. Decided to go back to Apple Music because of it's UI. I still much prefer the features that Spotify has to offer.
I use it only because quite a few artists I like to listen to have their albums on Apple Music. Spotify either didn't have them or had delayed access to them.
Some like it, some don't. I haven't even done the trial period. I don't want to go with Family Sharing with just my wife and I. I like our set up as is. So Music isn't worth it for me. I have Spotify and TuneIn Radio Pro. I can't stand Beats1 radio!
You can stream music played via Music from a device connected to a Bluetooth speaker. I regularly listen to Music playlist via a Bluetooth connection between my iPhone 6S Plus and my Bose Soundlink Mini II speaker.
Am currently testing the free three months service. Suggestions work fine, and the chance to listen to all the music you want is appealing. They say streaming services are the future, we'll see but for now Apple Music is doing fine for me.
I'm still on it. $15 a month is great price for the whole family to have access. My kids use it the most. My husband even found an Apple Music app on his LG G3.
