1.The Spotify Windows 8 mobile app does not have a radio feature. This is the reason I use Spotify on my computer and used it when I had an Android phone and an iPod touch! Until this feature comes back, it is worthless to me on my phone. I cannot afford Spotify Premium.
2. Any time I try to log in with my username instead of my Facebook account, I get a login failed error: "You need a premium account" (409). I had no problems logging into my old Android phone with my username, so if this is intentional, I don't understand why.
