I asked this in GQ but got no response.. perhaps this is a better place to ask.
I'm trying to track down the song that's playing in the scene where the main characters have a dance-off at a gas station. It has a rap beat with a mariachi tune, and the characters comment on both parts while they're listening to it in the car.
If you've seen it and happen to know what the song is, could you clue me in? Or if you're about to see it, could you do me a huge favor and write down the soundtrack listing from the credits?
