TIK TOK by Ke$ha is alot different to DOWN by Jay Sean because it is more funky and upbeat Jay Sean's song down is more of a relaxing tune but is not that relaxing compared to man in white! that is the big difference between Ke$ha's song TIK TOK.
Tik tok is a good song, for most people. If you are cool and like listening to different songs then you would like the song tik tok. It isn't a bad song but it isn't great either. Of course lots of teens and pre teens like myelf, love this song and would prefer it than Brittany Spears.
