I really don't have a प्रिय anything because I प्यार so many XD but I'll just choose बिना सोचे समझे ones from my 'short' list: Band- Asian Kung-Fu Generation Singer- Utada Hikaru (video)
Uh,I guess NeverShoutNever (but it's a one-man band) या The Ready Set (also one-man band) but no nevermind I like Linkin Park. My प्रिय singer is the guy in the following video. (look down!)
