I actually like all star by smash mouth
You like there songs only or you like the band Smash Mouth?
No it's the whole band I like, I really think their songs are really fun to listen to
Great! Many people like Smash Mouth too. If they are one of your favorite bands it's cool for you to express that.
I will try to convince them to do a reunion show. That is all I want for my birthday.
That would be really cool to have a  concert on your birthday. Good luck with your idea!
