Christina Aguilera spent this week releasing details bit by bit about her upcoming single and album release. First she showed off the cover for her forthcoming "Not Myself Tonight," with the promise of another surprise coming within 24 hours. It wasn't a full-length version that went up, however, as Xtina only posted the track's lyrics. We then got a peek at her upcoming album art, and today she's shared a 15-second snippet of the single before the whole version comes out Tuesday. It's quite the buildup to a song's release, so tell us what you think about the wait for Christina's new music — does it make you excited or annoyed?
