Shakira used to annoy the hell out of me now she's my favourite singer

I used to hate Lady Gaga and Christofer Drew Ingle (Never Shout Never) but now, I LOVE them.

Cheryl Cole used to annoy the f*** out of me but I like her more now. :)

Not really. Personally for me, I tend to not give musicians second chances. [I know, I know, really bad thing to do.] If I don't like a musician the first time I hear them, then I end up not liking them. So I honestly cannot think of an artist that I hated but now I love. An artist has got to prove themselves to me, otherwise I'm just simply not a fan.

Yes. Eminem and Britney Spears.

^^Eminem too. and Tinie Tempah

lol @Martyrockz12, thats the complete opposite for me. i used to like Cheryl Cole but now i cant stand the woman.

I used to dislike Jennifer Lopez, but now I really like her. :-)

Kesha before was the singer that I hated more but now I like her.

Oh!!! It makes me cry :'( I hated Paramore... but that was because I'm very weird so I have never heard their music, just reading about them in magazines (there was nothing bad about them but I hated that magazines were full of them)... Paramore is the best band ever...
And I used to dislike Nightwish (after listening to "Amaranth")... I was like "Metal, UGH!!!" xD But i changed my mind about one year ago, when I listened to "Nemo" :D
