For example European music, Italian music, American, Classical music, R&B music, Rock music, etc.
I do not often listen soundtracks completely, sorry if it’s the only one I’d mention.
Otherwise they are plenty of "ambient" sountrack, I’m not sure they are all worth mentioning.
Some stuff are dark, or sad, I’m not sure this is best to relax.
I remind I liked Pan’s Labyrinth by Javier Navarrete.
I do not consider Rock as relaxing.
human stain by rachel portman
secret garden by zbigniew preisner
unfaithful by Kaczmarek
winter guest by michael kamen
Comme les 5 doigts de la main by armand amar
away from her by jonathan goldsmith
fireflies in the garden by navarrete
beyond rangoon by zimmer (yes, zimmer)
others….
relaxing (for my taste) is one of my major criteria, as relaxing mostly is harmonic…
i would not at all be able to place those in time though, retro 60ties or anything. sorry.
