I recently did a trial of Deezer and must say its heaps better than Spotify. Transferring my music from Spotify to Deezer was really easy and almost everything managed to get on there, however the mobile UI is sluggish (selecting a song takes agessss) and can also be buggy sometimes. High res is also there, but I haven't really heard a huge difference. I would still recommend this over Spotify any day.
