Does anyone like BtoB???

I have a few friends who does not like BtoB but I don't know why. Today, I let my friend hear BtoB's song irresistible lips she said it was nice before knowing BtoB sang that song but after I told her it was BtoB she said it was so-so. Why don't they like BtoB??? I'm not expecting her to like which ever group I like but what is wrong with them???

Can anyone tell me???
