How to set loops on android?

[Shannon]

I just use one of the many music player apps, and create a folder with multiple files that I number, and then play that folder (set to play once per folder) or a playlist the same way.  This also allows me to have a little variety, I prefer the playlist to alternate between the ocean and trickling stream versions of a given sub during the day, of if I'm going to nighttime route, I may have the first one or two have sound and then the rest be silent.

Interesting idea, thanks for sharing with us!
