Music select for both players?

When a player selects a song on the music select screen, or pick random music, does the other player hear that selection during the match or are both players’ choice independant?

Each player hears the music they selected, independent of the other player’s choice. Player 1 could pick Inferno to play, and player 2 could pick Tiger’s Lair, and they will hear those respectively selected tracks on their machines.
