I'm curious to how long you have to listen to a track for it to be scrobbled? On the Last.fm application you can set it to scrobble at 50% of the total track length.
There's not a way to do this in scrobbl. According to last.fm's guidelines you're supposed to scrobble when: * The track must be longer than 30 seconds. * And the track has been played for at least half its duration, or for 4 minutes (whichever occurs earlier.) This is what scrobbl does, give or take ~10 seconds latency.
(It waits though until you start the next track before sending the track so that the 'now playing' & 'just listened' information on your profile is correct.)
