So far I’ve tried Metrolist, Outertune and Kreate, and none of them can.

I assume this is a limitation somehow, but asking here just in case there is an app that can.

TIA

Edit: I’ve looked at this open source music streaming list and tried SimpMusic. And hey presto it can do what I wanted to do.

The issue for me with Metrolist and Outertune is that it can only do local playlist that can be synced to my YT Music account. It could mean that say if I save my “MUsiiic” playlist from YTM as a local playlist, then enable sync to YTM, it would create double playlist.

I assume SimpMusic does the same somehow but it looks like I “turn on” save to local and sync it back to YTM. I checked and it didn’t make duplicate playlist.

Edit 2025-05-28: One flaw – not a giant one, but is making me look again – that I found is that the sleep timer cannot do “end of song”. So close to perfection, but this is a feature I use a lot. I’ll have to look into their issues and see if someone already asked for it or not.
