I'll start off with:

Trouble - Ray LaMontagne

At first I used to think "sod off you raspy voiced fool" whenever it came on the radio.

Now I love it for the beautiful, beautiful song that it is.

Untouched - Veronicas

Most of whitney's old stuff. I wouldn't say i hated it. I just never gave them a fair chance.

girls aloud's music.

The Saturdays - Issues
Lady Gaga - Just Dance
Little Boots - New In Town
Black Eyed Peas - Boom Boom Pow

Black Eyed Peas - I Got A Feeling

Taylor Swift - Love Story

I agree with that. Whenever it came on the radio or telly i used to switch channels, but after i bought it on a Now compilation i fell in love with it

David Guetta ft. Akon ~ Sexy Bitch/Chick
Dizzee Rascal ~ Bonkers

Lady Gaga - Poker Face
La Roux - Bulletproof

Those are the two most recent ones.

Don't love it but the Sugababes' 'Get Sexy' seeing as I was going to have to buy 'Sweet 7' to get my Jade Ewen fix I listened to it on a loop until I could stand it.

Poker Face and Just Dance - Lady GaGa
Love Story - Taylor Swift
You Rock My World - Michael Jackson

Bonkers - Dizzee Rascal definately...
Fight for this love - Cheryl Cole

Absolutely loathed FFTL, but it's a grower.

have to agree, it's damn catchy.

first one that springs to mind for me is 'bleeding love'.

Fix you - coldplay.

Thought it was such garbage when I heard it on the radio, then I heard a barman singing it to himself as he cleaned the bar and it took on a new life for me.
Random.

Pixie Lott - Mama Do

Any Christina song - I HATED her when I was younger - I was very much a Britney follower.

In my old age, I can see that a lot of her songs are amazing.

Oh and Black Eyed Peas - I got a feeling - hated it when I first heard it. Now think it is major choonage

yeah i remember hearing it so many times on the radio when it was first out and hating it because it was a bit childish, but all of a sudden it came on the radio once and i couldn't be bothered to go through other radio stations to see what else was on, i just listened to the song, and almost in an instant, something about it totally converted me and i've absolutely loved it ever since.

fight for this love - Cheryl Cole

I Gotta Feeling by Black Eyed Peas from Current charts.

An 80s Song I hated when it was 1st Released, which I Love now is.

Ride On Time by Black Box.

apparently i used to kick in the womb whenever that was played

Boom Boom Pow and Fight For This Love - Hated Cheryl's song when i first heard it but love it now - deffo grower

David Guetta Ft. Akon - Sexy Chick

awwI just got this image in my head of a baby having a party in the womb

haha, that would've been me

Anything from N-Dubz, they look so wrong but sound so right. As a 33 year old male, I feel dirty for liking them but cant help it.
