Using a more traditional definition of pop.
In our wonderful indie world of new bands we sometimes forget that mainstream music can be fantastic. These are all rather excellent...

Will Young - Friday's Child
Amy Studt - False Smiles
McFly - Room on the 3rd Floor
Kylie Minogue - Light Years
Texas - White on Blonde
Britney Spears - Oops I Did It Again
Keane - Hopes and Fears

Surely other people here like POP too?
