Artists with () means I already know and enjoy their music, I just haven't got those artists in my libraries yet.

1. Keri Hilson

5. Freddie Gibbs
6. Chrisette Michele
7. Pleasure P
8. Frank Ocean
9. Glenn Lewis

and a bunch of stuff I already heard and didnt like

So much TRASH

Most of mine are made up of European female vocalists and indie pop / alternative bands. I find most of these recommendations quite interesting.

Natalia Kills
Ladyhawke
The Ting Tings
Little Boots
Rye Rye
Oh Land
Paloma Faith
Miike Snow
Charli XCX
Robyn
Birdy
Kate Nash
Neon Hitch
Girls
iamamiwhoami

Listen to Charli XCX, iamamiwhoami, Girls, Oh Land, and Robyn.
Stay away from Natalia Kills, Kate Nash, Neon Hitch, and the Ting Tings.

Thanks!
I heard that Natalia Kills is terrible. Is that true?
And I am not into Neon Hitch.

Monica - Yawn. The weak link in the r&b trinity.
Keyshia Cole - I know nothing about her. Should probably give her a go sometime.
Ashley Tisdale - Heard her singles. No thanks.
Kelly Rowland - I like a few of her songs.
Mya - Moodring is an amazing album.
Faith Evans - Probably should check her out.
Jessica Simpson - "A Public Affair" is amazing. I don't think I'm missing much other than that. Her sister >>>>>>>>>>>>>>>>>>>>>>>
Richgirl - "He Ain't Wit Me Now (Tho)" is only like MY FAVOURITE SONG EVER!
Emily Osment - Basic.
Jennifer Hudson - I literally listened to "My Heart" like 5 minutes ago so...
Danity Kane - last.fm don't try me. Now you KNOW I listen to Welcome To The Dollhouse on the daily. Flawless LP.
Paris Hilton - dshbudfbhgf GIRL, PARIS IS LIKE MY FAVOURITE POP ALBUM OF THE DECADE.
Toni Braxton - Meh.
Solange - I've heard good things. Should try her out.
Christina Milian - She has a few hot tunes.

The second page of recommendations has Jessie J and Pixie Lott on it so I'm not even going to go into it.

Also, this would work better if I knew how to make last.fm scrobble my iPod plays. Right now it only scrobbles Spotify and iTunes.

Well Ipod plays always **** up and are only accurate 50% of the time you do them so you're not missing out on much.
She's like a derivative form of Gaga that makes typical Pop music that sounds like it's trying too hard to fit in. So yes.

Pixie lott - no
The saturdays - no
Sophie Ellis-Bextor - meh id need a good song to convince me
Dominique Young Unique - who?
Dannii Minogue -
Remy Ma - meh
TLC - dno
Ashley Tisdale - nah
Foxy Brown - meh
Amanda Blank - idk
Jackie O - no
Sugababes - ew
Little Boots - ewwwwwwwwwww
Eve - when im not lazy
