Almost

When I start playing a song, it shows up on last.fm as being 'currently listened to' but after some, maybe, 10-20 seconds it disappears again from last.fm and doesn't show up again even when the song has finished.

So at least the connection to last.fm works but there seems to still be some problems with the functionality (at least for me).

I'm using version 0.2.3 of mafw-lastfm. I just installed it, entered my last.fm credentials in the main settings and then rebooted the phone just be sure the mafw-lastfm daemon got started.
