News: Last.fm has released Boffin (tech demo) an app that scans and shows the tag cloud of your local music.

I'm having trouble with the ipod scrobbling. Also, it would be amazing if the app had artwork look-up.

For those using Windows, there's a plugin for foobar2000 that does roughly the same: foo_lastfm_radio.

This means you get with global hotkeys (eg: 'next track', 'pause'), DSP filters, lyrics display, etc.

Excellent little App! Great Work!

I use iScrobbler mainly to submit tracks that I've listened to on my iPod, and I've found that the 2.0 versions are unreliable for this so I've stuck with version 1.5. Version 1.5 does everything I need.

This little app has become one of my "must haves" Last.fm is an extremely nice service and I listen to the radio (whether it be tags or Similar Artists). The official Mac client is really clunky, and often problematic. iScrobbler is a very nice alternative. And since 2.x can now play radio stations in iTunes it is unnecessary to even have the official client around on my Mac.

Thanks Damaged for your hard work!

If you want to display album art while listening to a radio with iScrobbler, you can open a web page to snappradio and login with your last.fm user name.
Not very practical, but it works. :)
(You'll also get some flickr photos that should be related to the song, but they seem very random to me...)

@cayayofm : go to Growl preferences, find the 'iScrobbler' app in there, and uncheck the ' enabled' box for the track change notification.

How can i sop the notifictions when a song starts playing? I have CoverSutra for that. I can't seem to eliminate this.

Quicksilver can be used to quickly call the 'tag track' dialog, you'll just need to put this in a script:
<code>tell application "iScrobbler" to tag current track</code>
Put the script in here for example: ~/Library/Application Support/Quicksilver/PlugIns/iTunes Module.qsplugin/Contents/Resources/Scripts/

you can choose to hide your recently listened tracks by going to 'Settings', in the Privacy tab, and check "Hide real-time listening information".
