Music rip-off?

Ok, so I read an article about this, and thought I'd check it out for myself:
Recently a Dansih rapper, by the name of "Jooks" have become radther popular with this song:

The thing is, that riff/beat sounds quite familiar? Now check out this song: (forward to song at 1:04)


That's Oukast - Hey ya

And well, just for the heck of it, I made this little mashup:
I got the instrumental version of the "Jooks" song playing on the left deck, and Outkast on the right deck (tried to filter out as much Outkast music, as I couldn't find an acapella version of the song):

I know that it's not very good, and that the beat doesn't really sync up after the first line, but I thought it might be fun... Comment please :D
