I just said this on Twitter but I'll say it again.
Tanya shouldn't be afraid to have a big name feature on a promo track. I think people on here assume that if she'll have a big Hip-Hop artist on a track that the track must be a single or something.
She shouldn't also be afraid to drop tracks that won't make the album, especially if they're amazing. She did it with RIM and all of that, but it would be epic now since she's back on her ****.
