Use iScrobbler instead: http://www.last.fm/group/iScrobbler
Still scrobbling tracks for me using 7.7.1
I was using the last.fm app to scrobble it's broken now. See the link above four plus pages of complaints.
After d/l iScrobbler like FFW recommended it works great. Again thank you for pointing me in the right direction.![]()
Isn't it designed to be used with iScrobbler anyway? I know when I got last.fm I got iScrobbler that same time.
I used this which is what it links you to directly, I didn't know any better.
