I used to have the the same unreleased that CristalCastles and some BTD demos, my Pc broke and i lost everything...And I discovered that Lana didn't liked the fact that the musics got leak...so I didn't gave very importance in getting the music back...
I don't know if she's shooting DP, she said that it will have a video, but I don't know if it will be a single, because she has the BTD PE in November, and I think that she might release one single in september...
