LastFM’s audio fingerprinting

LastFM are attempting to create a database of clean metadata about music – and provide a free API that lets you pull down definitive information about audio tracks…the classic problem with audio metadata is that people add their own metadata to content that isn’t that accurate – think spelling mistakes, think capitalisation – and this makes it hard to uniquely ID content (makes it hard for humans anyways).

So, the good people at LastFM have created a piece of software that scans your music collection, and farms all the information about it  over to an uber database – get the software here.
