I agree that Baby is reli a hit song.....but i personally hate it a lot....
there are a lot other great songs that are sung by Justin Bieber, such as That Should Be Me and One Less Lonely Girl
if u like his songs....u should definitely watch his MVs....they r so *****ing funny (but my friends said his MVs were romantic....)
another good choice must be Lady Gaga....dunno whether u know her songs or not.....i would suggest you listen "Telephone"
here's my favourite: Whatya Want From Me and Mad World by Adam Lambert.......even my friends that hate Adam Lambert said these two songs were great
Starry Eyed by Ellie Goulding is quite ok.....but her style is a bit weird
