Well I've got a couple songs to contribute to the shitlist.
Firstly, this song is We Like to Party by the Venga Boys. Its an incredible popular song, its the six flags theme song, and it can be verified that it is in fact the Venga Boys' song through itunes, as it is one of their most popular.
Secondly, this song is a song used in the madness series by Krinkles on newgrounds. If you do not recognize it, just watch the series, or a PM to krinkles could easily confirm that the song is not by the artist that submitted it.
Third, this song is the actual Pokerap from Pokemon. The fact that this is confirmed can be easily confirmed by anyone who ever watched the older pokemon series, as the song was played at the end of all the episodes, and is obviously copyrighted by the Pokemon company. In addition, many of this guys songs are stolen, such as this one, which is the original Pokemon theme song. This guy obviously did not write the theme songs for Pokemon, and the fact that he is submitting these songs is a MAJOR copyright infringement.
PLEASE mods, delete these songs! If I haven't given enough proof, I'd be happy to offer more, as this kind of shit pisses me off.
