Jamie T - Emily's Heart; Johnny Flynn - Hong Kong Cemetry; Newton Faulkner - Gone in the Morning; Paolo Nutini - White Lies (Actually, anything by Paolo is the shit) :)
Those are just to name a few of the great artists that can be found on this amazing site that I found. I really think you'd REALLY enjoy the artists found on the station that I'm always tuned in to. I'm gonna try to insert the link in here, hopefully it will work.
If it does, ENJOY! Oooh! And David Gray and Ray LaMontagne are goodies too! :) James Morrison and Laura Marling - Blackberry. I think you'll like that one. :)...too. ;)
