A lot of albums are coming out this year from Hollywood Records.
Vanessa Hudgens album is coming out this spring. She is almost done recording. Jesse McCartney's album is coming out in April (according to his myspace or website...can't remember which). Raven's new album is also coming out sometime this year too. There has been a bunch of info released about some of the people/producers she is working with. The reason they are not listed is because their albums don't have a release date yet, therefore they won't have a single/album release date yet.
"See You Again" is a song from Miley that is doing very well on radio (made top 40) with no ads and no video. "Start all Over" is apparently going to be a single because Miley just filmed a video for it. And "Reach Out" looks to be the single off the Dignity re-release. It sounds like current/future songs that Hollywood is going to release in the early part of 2008. January-March probably.
Here is a bigger picture. You can see her Seventeen cover a little better. She looks really pretty on the cover (from what I can see).
