I would be interested to know if a higher resolution version of this music can be streamed or purchased online (digital downloads only).

maybe ask the channel who posted it.
wont be surprised they do it themselves...

also got stream ripping sites that can do at 192k... but doing 7hrs is unlikely...

THanks for the response. I tried to establish contact with the channel by sending them an email but couldn't figure it out how to do it. I'll try again later.

I have searched everywhere and it seems that they may be creating or recording the music themselves as the music can't be found anywhere. If the continuous music are available split to individual tracks it would be much better. There is the sound of raindrops added to the music and it would be even better if these sound effects are omitted from the music.

Usually they combine alot of artist music into one long format. Unlikely to buy unless individual track one by one.

Not advocating or encouraging, but there are sites that can rip youtube videos and convert to audio format of different qualities and formats, even snip the video based on timestamps.

However, some videos may be restricted and won't be rippable. So you'll have to try and test to see if the ripping even starts or not.

That said, better ask the video owner if they would upload on spotify or some other platform. Some of these creators do. Especially given now that AI can produce these music easily.

Just comment on the video. And see if they reply.

i tried to search for AI music detector but hard to find. i have suspicions it's AI generated music but cannot verify/debunk

The source (audio file) downloaded on Youtube is usually low resolution or poor quality and it's usually combined with the video. I'm looking at higher than 320kbps quality, either in WAV or AIFF format or at least Lossless. 320kbps is only good for mobile (earphones and headphones) but lacking in home audio.

Also, the combined music in the Youtube video above is duplicated or repeated. It's just several tracks repeated in the long video, and during the transition between tracks it is not smooth and choppy as some tracks are abruptly cut off (before it ends) as the new track starts playing. It's poor editing.
