I use a Sansa Clip Zip with Rockbox, and recently an issue has come up relating to the Last.FM log feature. I use LogScrobbler to upload my log, and when I check Last.FM no tracks that I have recently listened to on the player have been listed. Reloading the database, turning off the logging and then turning it back on seemed to work once, but now, even though LogScrobbler says the sync completed, the tracks are not listed at all. Did Last.FM make some new change that locks out applications such as LogScrobbler or is this my problem? My firmware is the newest dev version available, if that's any help.
