I know, kind of taking a step backwards. But, I don't know of a streaming service that will send high bit-rate multi-channel audio through your phone. Try a few of your favorites on disc and see what you think. The unfortunate part is there are good and bad examples of multi-channel recordings. Some did it right. Some used it as a gimmick to place sounds where they don't belong. Read reviews on a recording before buying...It would be pretty funny if I started driving around with a huge book of discs like it was 25 years back.
