a song question...

so yeah, everyone is asking for song questions about that score one and the middle part of the movie. (yes i looked all through the questions about songs so i dont have to repeat. lol) all i want to know who plays that song from the beginning where the character johnny is playing that video car racing game. then the song appears again in the end of the movie when the credits start showing up. if anyone knows, let me know. i'll appreciate it.
