Re: I can owe?
I wouldn't get too stressed about song lyrics. They frequently don't make sense or they are ungrammatical. I have looked at the rest of the lyrics around that phrase but I still can't work out what he means.
If anyone else wants to have a go, this appears to be the chorus:
"are you having a good time
with your friends and your french wine?
so now i'm gonna warn ya that there's only so much i can owe
are you having a good time? yea yea yea"
