I didn't mean to say that ES games didn't have amazing songs though. Rather, in addition to them, they had a lot of boring ambient tracks with no really memorable parts in them. In the previous ME, DA, KotoR, Neverwinter Nights and KotoR games, almost all songs were memorable and unique, and more importantly, almost all of them were good on their own, even outside the game.
I mean, take any random ambient track from KotoR. This is just the first random track I stumbled upon on Youtube:
There are so many elements in this music, it catches your ears and you remember it forever since then. This is something many tracks in most open world games don't have, sadly.
