"Tell me.."

I've been trying to find this song, I heard at Kohls.
I just remember it includes some lyrics I caught, but the words are jumbled so I couldn't get all of it memorized.

I heard:

"tell me...[why you..have to go and]........................What'll I do now?"

[brackets mean I'm not even sure those words go there]

It's a male singer, upbeat. I think he's solo but it may be a small band.

As you can see, I don't have much to go on. But I appreciate all the help I can get on this!!
