Meta-iPod it’s a small freeware that can clean up the iTunes library with as many features as a Swiss Army Knife, or so they say on their page:). It can recover ratings and play counts from your iPod,Â track down files or folders gone missing, analyze all data sources with your music to put the pieces back together. Can also fix files that have been moved and thus unlinked from iTunes.
Then, meta-iPod will search iTunes to see if that track has a duplicate on your PC. If no duplicate is found, then it will check other data sources to see if it can find the tracks location automatically.
