this is happening katycats As much as I would like and want this to happen, I'm still skeptical until someone provides a reference from a reasonably reliable source.
*Points to Muzu.tv*
"EMI signed a deal [with Muzu.tv] on 16 January 2009 which permitted the website to feature more than 5,000 videos." - Only official people an upload to that website, therefore it is at least 'reasonably reliable' I think you're just waiting on Official Confirmation from Katy or Billboard.
@Conalae: thanks for clarifying. I think I'm a little less skeptical now.
I think it's because of all those tweets I have been receiving that "Part Of Me is confirmed as the next single/being on the re-release, etc." only to find that was just a mention on some fan message board that has made me view these claims with a "questioning arched eyebrow", as Katy would put it.
Also, nowhere in those ET videos does it ever mention POM as being part of EA's commercial or promotional videos for the game. Nor has EA ever used the song in their videos (the ones seen on YouTube are merely overdubs).
However, there is one video that does attempt to synchronize POM's lyrics with the EA promotional video by overdubbing the track with the vid. If you look at Katy's mouth movements, I think they closely match up with the lyrics to POM.
This video is also linked to a pop blog titled "Pop On & On", which is also reporting that the track is rumored to be the next single off TD Complete Confection. Don't know how reliable the site is, but it does appear to have some credible articles. http://poponandon.com/previously-leaked-track-part-of-me-to-be-released-as-next-katy-perry-single
So the speculation is indeed heating up. However, I would feel more comfortable about this if the news did come from Katy, her record company, or established sources such as ET or Billboard. Just me I guess.
