Recommended. Highly.
OMG…this is freakin’ BEUTIFUL… 
Ah, yes, that piece. Yeah, I’ve had it for awhile, and I still am not tired of it. Still, I prefer the Incredible Singing Robot (Robo’s Theme remix with lyrics).
The vocals scare me.
If you like Vocalized OC Songs, check out ANYTHING by Dj Chrono and “Zelda - The Music of my Groin”
