i beg to differ coz that's just bias from my point of view.
dbsk can sing (and not just 1 or 2 have great voices) unlike what popular perception of an idol group is. i kinda hate it that their concept was set as idol singers coz they're more than just a pretty face and great dancers. labellings have got to go.

i used to think like you. idol groups are just pretty faces with no personality and not that GREAT voice. so i used to shun the groups with this label. i happened upon dbsk and superjunior by chance. and i liked them. then i found out that their concept was idol group. sigh. but i still like them.
