While Tune Sweeper does most of these, it is a real laggard. At launch, Tune Sweeper reads the iTunes Library.xml file, which is accessible to third-party apps. With my library of about 65,000 tracks, on a fast Retina iMac, it takes about 3 minutes and 45 seconds to read this file and display the main interface.
