The previews of Katy Perry’s re-release of 2010’s Teenage Dream, entitled The Complete Confection, has been released online. The new additions to the album include the number one single Part of Me, the Tricky Stewart produced Dressin’ Up, the Bonnie McKee penned Wide Awake and Tommie Sunshine’s Megasix Smash-Up of the six singles from the original release of the album.

Dressin’ Up has probably been the most anticipated song by many since it leaked online sometime last year. The leak was a small clip of the first verse and chorus. It’s believed that at the time, the rest of the song had yet to be written. The finished version of Dressin’ Up keeps the basics of the original demo but has a more polished production which almost takes away from the edgy, rawness of the demo. Had I not heard the demo, on first listen to the finished product, I’d have called it E.T. Part II. This is not necessarily a bad thing. However, the chorus is given an extra punch to become a bit of a stomper and leaves the original demo vocals untouched. The vocals on the verses have been given backing vocals but they sound a bit muffled under the production. Overall it’s still an excellent track and it will no doubt be a huge hit for Katy – and we’ve still yet to hear the middle eight.

Wide Awake is the other previously unreleased track. It was apparently originally recorded by co-writer Bonnie McKee. It’s a gorgeous electro-pop ballad that also cries for a single release – like almost every song that hasn’t been a single yet from Teenage Dream.

The Complete Confection will be released on March 26th through Capitol Records.
