I love so many artists and styles of music. I'm listening to a fair bit of Jazz and Easy Listening at the moment, Billie Holiday, Ambrose, Madeleine Peyroux.
My all time favourites include:
Duran Duran
Arcadia
Power Station
Adam Ant
Beatles
Stones
Kinks
Dave Clark Five
Status Quo
Peter Frampton
Humble Pie
Gary Holton
Sparks
The Sweet
Creedence Clearwater Revival
Elvis
The Who
Medieval Babes
Some others as well, but I will probably add those at a later date.
