That song that played at Kohl’s Department Store?

Before they entered holiday mode with the songlist, I’d say up until the end of October at least they were still playing this one song I can’t seem to find ANYWHERE, and it’s driving me CRAZY. I don’t know the name of it, or who the artist is, all I have are some snippets of the lyrics:

‘Sunshine through the rain’
‘I accept everything that I can’t change’
‘Don’t be discouraged’
‘Look in the mirror right now’

(Wordings might be a bit off, couldn’t make out clearly from the store’s speaker phones)

It’s sung by a female, with a small part sung by a man in the middle. Seems kind of pop/r&bish in style, don’t know. Also, it starts of with a piano solo type thing, I think.
