I heard a song in a Wal-Mart store in Canada a couple weeks ago.

Female singer, Pop-R&B style, mid-tempo - not a slow song, but not a real dance song or anything, the chorus had the word "dreaming" a lot so i suspect that may be the name of the song. Also sometimes said "I keep dreaming" so that might be the title too.

That's all i got, i couldn't make out any other words. Sounds like something that would be pretty recent (in the past few years)
