As ambient music goes, that is beautiful. YouTube has many ambient music channels or mixes that last for many hours, I have it playing all night, helps me relax and chill. I can recommend YellowBrick Cinema. The older I get, the more I appreciate the chill/ambient genre. When I'm out driving, I'll have Smooth Chill on, problem is its DAB only, and I tend to lose signal in many parts of mid Wales.
Glad you like "Ambiant Otaku", Rob. Strange that Ambient was spelt that way. Tetsu Inoue disappeared around the time of the Tsunami there. Still he made some wonderful music and it would be great if he came back. "siberian ambience" is a great YouTube channnel.
I think the spelling comes from the french version of the word Mike. English Translation of “ambiant” | Collins French-English Dictionary (collinsdictionary.com)
If you upload mp3's to your phone, you can "bluetooth" them to your vehicle stereo or connect via a 3.5mm to 3.5mm male/male Audio Cable. (From aux on the stereo to your phone's headphone socket.) I use one with a 90-degree connector at the stereo end to minimise damage. Places sell them cheaper too. Hope your stereo and the phone have these female sockets!
