Suggestion to play subs on Android?

[JaneM]

I'm currently using Pi Music Player on Android to play my subs on my old smartphone I have hooked up to speakers on my bedside table. I have it set to continuously repeat the one ultrasonic sub, but I'm finding when I check it occasionally that it has stopped playing! It's very frustrating. 

So I'm looking for suggestions or recommendations of other players that will play continuously.

I have used vlc in the past without much trouble. @Shannon recommended Pulsar and I have found it to be a very good app.

Thank you, I'll look into those suggestions. I have been trying You Tube Music which appears to be working, no random stopping. Every time to check it, it's still playing. :-)
