Sean Garrett: "'Check On It' was actually on the Pink Panther soundtrack. That was a really big record, too. That came out of the studio sessions and was written going out the door. That track wasn't even taken that seriously. It was just a record that me and Beyonce worked on really quick. We probably did that one in 15 to 20 minutes.
"That was the great thing about working with Beyonce because she utilizes every song. She has all kinds of packages that she's going to release, re-release, remix, or have an idea to package all of the records to where they can all be effective. This wound up being something really, really big."
