Fans believe that the production for the album was done by Max Martin and Shellback! A few green and orange billboards were put up yesterday (most notably in Times Square) with a QR code that linked to an official Spotify playlist made by Taylor Swift. The playlist is called "And baby, that's showbusiness for you", and it's made up of songs from previous albums of hers that were all collaborations with Max Martin and Shellback. This has led fans now think that she collaborated with them to make TS12.<br /><br />We still don't know what the easter eggs with her logo are in the background of the New Heights podcast promo video clips that have come out. There are at least four boxes (or what appear to be boxes) in the bookshelves behind Taylor and Travis that are different colors (white, orange, purple, and red) that people are very curious about...<br /><br />Finally, there is possible buzz that there might be some sort of collab with Sabrina Carpenter, either on Sabrina's upcoming album or Taylor's? There's a picture of the two of them onstage in New Orleans in a carousel of photos Taylor Nation posted that ended up being promo for The Life of a Showgirl. Can't wait to learn more on New Heights!
