i love my MU, i use it all the time, on line and off. i use it more than the music app. its a best way to save space on he memory stick, i would like to see eather the music app updated to play visualations or if MU had visulations.
i just typed in bing spotify app for ps vita i gotta say it would be "EPIC" if they (sony) put the app out there for vita even ps3 users cause 1. spotify is legal 2.its free via wifi 3. there may be ads (sponsoring spotify) which you could avoid by from experience on my PC selecting a new song right b4 the current one ends it voids the audio ad !!
Sony for the luv of all that is Holy get permission via licensing to host Spotify over PSN
FYI i may play more xbox live than PSN but gotta say looks like PS4 is gonna be top dog next gen !!!!
