XM radio commercial song

OK so there's this XM radio commercial, and it goes through a bunch of classical songs, and country songs, and random songs to you know, show what they have on their radio. The last song is a rap song, the lyrics are: I was chillin', right around my ______ . 21st east side of da beach. (end of commercial). It is a really good song from what i heard lol. So can anyone tell me the name of the song and the artist plz?? that would help me soooo much.

Try... Snoop Dogg Feat. B-real - Vato
