Thank you, thank you!

One more please.....

Female singer.
The song sort of has an Asian-sounding beat.
Some lyrics are:

If you think I'm blah, blah, blah, blah, blah, blah, blah, blah.
And if you think I'm blah, blah, blah, blah, blah, blah, blah.
I won't be by the phone.
(or maybe, I'll be out the door.)

Any ideas, please?
