Do girls actually like the jonas brothers for there music?

i find it ridiculous just how bad music is in this time.i mean imo i think music isnt listened to just because it sounds good anymore.like would any girl honestly tell me that they would still like the jonas brothers if they were 50 year old ,bald ,fat men?please tell me honestly because theyre music along with others in this day and age is all commercialized crap target to tweens that have never heard of real artists like nirvana,u2,zeppelin etc..thanks
