Does rob really sing?

yeah. he sang two songs for the Twilight Soundtrack. The director, Catherine Hardwicke, snuck in the songs. haha But he agreed that they fit into the mood of the scenes. They're called "Let Me Sign" and "Never Think". "Let Me Sign" was played during the ballet scene. And "Never Think" was played during the обедающий, закусочной scene. He has other songs on Youtube like:

I'll Be Your Lover Too
To Roam
Broken
Stray Dog
And a few more.

They aren't professionally recorded. Someone recorded them while he was Пение them, either at local pubs или open mikes.

I personally Любовь his music. He's very soulful and sincere. He reaches within himself and brings raw passion to the songs. They're very very soulful and that's why i like it :)

Yeah and he plays the Пианино and guitar. I hope he does not get fed up with all the Фан frenzy surrounding his Актёрское искусство and decide to go Главная (Britain) and only record music. would miss him so much.

ya he sing but he sounds like dying animal

Yes,he is singin a bit!I have the CD of Twilight Музыка and when i heard him singin it was so touchin..omg i was crying
some of his songs are :*I'll Be Your Lover Too
*Stay Dog
*Let me sing

Yes.
As Mandapanda said, he has two songs on in the Twilght movie.
I have the lyrics to 'Never think'.
At one point he was quoted as saying "Music is my backup plan if Актёрское искусство fails."
Hahhaha.
Well that didn't happen, and it ALSO help him get his Музыка out there.
Lucky, stupid, talented, jerk, plus he gets to makeout with a hot actress.
*Bitter*
On the other hand, he can't even leave his house without being attacked.
Hahahaha, just kidding.
