Lets your Walkman app scrobble to the official Last.fm app.
Warning! You need to open this app at least once to activate it.
App is based on what I figured out the original Last.fm Scrobbler for Xperia did, but it broke on the Xperia Z1 so I decided to hack my own solution. You can find the original app here: https://play.google.com/store/apps/details?id=com.mobilesolutionworks.semcmusic.scrobbler
Open source! Source code available on https://github.com/Ambroos/Xperia-Scrobbler-2013-Compatibility - I'm open for all suggestions!
Verified to work with: Xperia Z1, Xperia Z Ultra, Xperia Z, Xperia E Dual
Should work with all Xperia's using Walkman!
