I was thinking, has your computer ever automatically filed songs under really random genres?
My weirdest ones are 'sugar we're going down' by Fall-out boy being filed under emo, 'Swing Swing by the All-American Rejects under (152), 'In the air tonight' by Phil Collins being dance and 'Unfaithful' by Rihanna being Unclassifiable.
This is Windows Media Player by the way.
