You obviously get online streaming of full albums, curated radio stations and recommend playlists based on your listening habits on Spotify. It should absolutely be expected from a music streaming service in 2016. Complete checkbox features for me, especially when Zune did all that before. Smart DJ was a thing before Xbox Music even existed, but it's cool that Groove has it back now. Streaming your own music library is really cool, there's nothing like that on Spotify, so it's a clear win. But at least you can download and save any playlist locally (to phone, tablet and PC) with Spotify and if you really want to, even sync your own music/mp3s to your devices (via WiFi, too, just like Zune <3). e3: I just saw that most of the features you're talking about just hit the service in the latest app update. That's hilarious.
The last time I used Groove on iOS, the app didn't have a scrubber. That's right, a music app with no way to control the music that being played, other than skip/back and pause. To me, that's gutter trash tier. Definitely shit.
When I switched from my free Music pass back to a paid Spotify subscription (I still have a couple of codes, not sure if they're still valid, though), the app didn't even have an iPad version. But you made me curious, so I checked the app store. And lo and behold, there's still no iPad version. It's still a blown up phone app on a big screen. I don't see how that's acceptable in a cross-platform environment and it definitely pushed me from my free pass to a paid plan on Spotify. Win32 Spotify with touch is a better experience than this.
While OneDrive access is a fantastic option, it should be mentioned that you have to pay two subscriptions, if you want to access your library via OneDrive. It doesn't really matter if you get the storage through Office 356, it's still two subscriptions. It's awesome for people who have it anyway (much like using it on Xbox), but it shouldn't be taken for granted.
I like the tip for the HTPC, though. I'll definitely test this later. Hopefully it works well with a remote. I really miss the absolutely fantastic visualization from Zune.
e: The Zune Pass codes still work, lmao
