I think that tend to happen with Open World games, because you need some background songs and the small moments we have a score telling the story, which in the trilogy happened the whole time, so you actually managed to fit music with events and feelings, now you have songs that can be both playing when you are clearing that hard difficult enemy base, and when you are scanning that flower. I am a very song/music driven person, and I cannot state any of MEA songs had actually reached me.
Which then, affects the whole sense, in a way, of supportive emotional process. MEA is leveled, by my experience, to a bit more than ME1 when it comes to feelings. I think MEA is on the bad side of that comparison because it made me play around 100 hours to prompt some feelings to me, whilst ME1 sparked the same level of emotions on 20h.
