What problems do people have with Groove now on W10?Definitely happy with Win10 on Lumia Icon. Fast and zippy, runs great. Not going back to 8. Also glad I got Core player cause music app on WP continue to look terrible.
Xbox Music on 8/8.1 was terrible as it was always slow and unresponsive, particularly in comparison to WP7/Zune music players. Groove on my 950 XL however is quite good. It opens immediately, loads my music right away and scrolling through playlists/artists/etc is perfectly smooth. The only stuff I wish they added was more "discovery channels/playlists" like Spotify, but otherwise it works great for both my Groove library stuff and what I have on Onedrive.
