Help me identify this song!

Ok, I don't have a lot to go on... I was watching the music videos on iTV and this really cool song came on... with no identification whatsoever. It was kind of rock music. The music video was mostly stop motion painting. The rest was a guy playing guitar. I don't know a lot of vietnamese yet so the only lyrics I caught in the chorus were "mưa, mưa em" and i'm not certain about the em. Haha, does this ring a bell for anyone? I couldn't find any sort of playlist online for iTV.
