So I noticed that there were a few artists who were duplicated in the media player because of capitalization issues (The and the, etc.) So i fixed them up using my PC. The problem now is that the n900 media won't detect these changes, and it seems that I need to remove and rebuild the media player cache. I know that the files are handled using tracker, but what command would I need to use to have the tracker rescan and update all of the cache? Is there a cache file i can just remove to make it rescan? I'm not familiar with tracker, and all its options make it even more confusing.
