When 'Teenage Dream' reaches 10M certified units in the US with TEA/SPS (or whatever the acronyms they use these days are), they should re-re-release it as 'Teenage Dream: Diamond Edition' with a special iridescent cover (like PRISM deluxe), HOWEVER it'd be identical to the original 12-track edition of Teenage Dream, and they could release "Hummingbird Heartbeat" as a single in promotion of the new edition, and it could go #1, breaking Michael's record as it's from the original album.
