From the developer:
ManiaDB gets current song information from iTunes then searches maniadb.com, Amazon, Amazon Japan, cover.zzlzzl.net, and AlbumArtExchange.com. It shows search results in separate window. If song name or artist changes as a result of click, it will search again. This application is written with Cocoa.
