@HijoDeAguila, ACII had the best ambient soundtrack, each city had it's own variety of songs and it didn't matter in which sync/chapter you where, at rare times you where left with the sounds of the city only, in AC: Revelations there are times with no music at all or the same soundtrack over and over again, kind of annoying however i did enjoyed the "Byzantium" theme.
