What I really like about Spotify is that it's platform agnostic. I can use it everywhere, PC, Mac, iOS, Android, web and it got some neat features. Xbox Music is just this horrible mess that's worse at music tagging than iTunes, which is hilarious, in a sad way. The problem with Spotify on my phone is that it doesn't play any music. It tries to load the songs, but never plays a tune.
And yes, it's great to be back.
My yellow 920 arrived on Friday and I've been using it non-stop since I got it. Haven't touched my Nexus after transferring my data. It's great to use an OS that's so smooth. I also ordered a grey silicon case and a generic Qi compatible charging plate.
