I would love to have more music in game like in previous titles. The menu music in FM4 by Lance Hayes was brilliant and would love bring that or something similar back. I would also love to see an actual soundtrack with popular artists while racing in single-player mode. Go back to any racing game in the early 2000s, from NASCAR Thunder 2004, GT3, to Need for Speed underground. They all had amazing soundtracks with a veriety of genres.
Here are some of my suggested artists/songs:
Artist. Song
Chevelle. Hats off to the Bull
Static-X. Z28
Feed Me. Feeling so free
Wolfgang Gartner. The Champ
Deadmau5. Monophobia
Pendulum. The Island Pt. I & II
Authority Zero. Liberateducation
The Black Keys. Shine a little Light
Adelitas Way. Still Hungry
Alien Ant Farm. Let em Know
Trivium. Becoming the Dragon
I know these probably wont make it and they are only suggestions. I would just love to have an actual soundtrack back in the game.
