In the campaign, I've noticed that there are a few missions that, after beating them, the cutscene in the end had the same song that played throughout the map. I would love different songs to play during those cutscenes, any song that is different than the one I heard all throughout the mission. It's not really an issue, but it's variety. Act 5 Mission 1 and Act 5 Mission 2 are the ones I've come across that did that so far.
