From CherryTreeRecords I absolutely LOVE Tokio Hotel and I like Cinema Bizarre (Not my fav band at all but I can dig them, their music and their style. Luv Strify and Yu)
For the rest: there are some good singers vocalwise, like Robyn and Lady Gaga ( deffinitly not the barbie from Flypside. Pretty girl, annoying heliumvoice. Be a model, not a singer.) but their music itself sucks a**!!!
If you wanna hear good music listen to artists under Decaydance/Fueled By Ramen (Paramore, VersaEmerge, The Academy Is..., Gym Class Heroes, Cobra Starship, The Cab, Panic At The Disco .... you get the point) Tokio Hotel should have signed with FBR. That would have been superb
