Mars Volta
Mars Volta is a European electronic act, responsible for songs such as "Bach Song". This band is, understandably, often confused with The Mars Volta ( modern progressive rock band featuring former members of At the Drive-In). In fact, these two bands are entirely different and unrelated.
But, in fact, of the top 10 songs listed 9 are from The Mars Volta, most likely because of the bad tagging of most mp3s.
