1) Taylor has 
10 songs completely finished for LP5. She has around 5-8 demos of different songs also finished
2) She's been working with some of the best song-writers in the industry for this record. I won't reveal which ones.
3) No MM&SB songs are on the current tracklist, but she has worked with him this past year.
4) The album will be 2 discs, with a total of 23-27 songs. 
The first disc will be all about the art, then second being all about the pop. (

5) So far, the songs sound COMPLETELY different from any of her previous work, my source telling me strands of info similar to that which has leaked on the L Chat board.
6) The album is set for a late 2014 release, and they're in the process of coming up with a really cool way of releasing the album.
