Star Wars Battlefront Beta Soundtrack Speculation

Anyone here played the open Beta of the new Star Wars Battlefront?
It has some tracks right from the movies like "Imperial Attack" and also shorter motifs like "Vader’s Entrance", but also a lot of ones that sound exactly like Star Wars but I cannot place them.
The only track I can identify with maximum certainty is an alternate to "Battle over Coruscant" from the beginning of RotS.
Could these be alternatives to the cues from earlier movies, small teases from the new movie score, or completely original material for the game?
