cant think of any specific examples buuuuuut
anything anything anything from animal crossing, all the music is adorable and makes you feel safe (lol im a (BAN ME PLEASE))
legend of zelda: ocarina of time has some of the best music of any zelda game, but honestly, all the zelda games have great music. in fact, its a bit odd that the zelda games all have such consistently great music seeing as there are so many of them. heres to consistency!
frozen synapse has pretty great music, it fits the game quite nicely and makes the whole experience of playing the game much more absorbing.
i confess that a lot of the time i play games with the volume off so i dont wake up my parents, though, so im more than likely missing out on a great deal of awesome music! :(
