Why does DDR change author names?

[Goldenwind]

Examples, "Toxic" we all know is by Britany Spears, but on SuperNova they say it's by someone else.

"Faint" on SuperNova2 is by Linkin Park, but they say it's from Pegasus

Too lazy to get more examples, but you get the point.

Are they just using pseudonyms for the real artist? If so, why?
Or are they being cheap and getting people to rerecord the songs, so they can save money, and get someone elses name up there?

They're remixes by different people.

EDIT: Or maybe covers, i havn't played DDR:SN2.

They're covers. The artist that's listed is whoever did the cover.

Like Captain Jack. Centerfold was by J. Geils Band, and Captain Jack did a cover of it.

Like 'Genie in a Bottle'.
That song was by Christina Aguilera, but it's by some other group and featured on Ex 2.

Sometimes third-parties remix these songs (with permission from the original artist). They must have bought it from the third-parties and thought that they made so they did not usually include the original artist's name in the song.
