Automatically wash your iTunes music database with Rinse

Rinse doesn't really do anything that you couldn't do yourself (querying the Gracenote database, correcting spelling mistakes, adding album artwork, removing duplicates and so on) but it does make the task of doing them a lot less tedious. As well as being very easy to use, Rinse can be left to run without intervention in order to speed up the process even further. All in all, this is a very handy utility that can take the pain out of tidying up a large and messy iTunes database.
