Stacktrace I received from clicking on unplayable songs in am album too quickly, I assume this is related.

I'm not able to reproduce this, but just to be sure I'm not testing with the wrong songs, could you send the URL of some songs that don't work for you?

• Did you change the streaming backend by any chance? (the first option in the download settings section)
• Do the songs work in other YouTube clients? If not, this might be a region blocking issue or something similar on YouTube's end.
• Are you using a VPN or anything like that?

SpMp should log information about playing songs, could you find the logs for when song playback failed and upload them please? You can use a tool like Logcat or try capturing a bug report.

I don't think that's related to this, but thanks for reporting (I'll try to get that fixed as well).

Thank you for the reply. Here's a couple of songs that are affected.

• I'm using the default Youtubei backend. I also tried Newpiped but no song would play through it.
• I have tested on other Youtube clients, specifically InnerTube, ViMusic, and Newpipe. The song's wouldn't appear on the first two and Newpipe threw an error about being premium only.
• I haven't been using a VPN for this.

Here's a app log pulled from Logcat. The playback issues should be near the bottom.

Seems like the issue is not being able to play premium-only content then. I won't be able to support playing premium content, as it's probably DRM protected (and I don't have YouTube premium to be able to test anyway).

I've had a look at InnerTune (which I assume is what you meant by InnerTube) as it also supports logins, but I didn't see any code related to hiding premium content. Were you logged in to InnerTune when you tried it?

[talkingkittycat]

I was indeed logged into Innertune, though I didn't see any premium music.

Still, thank you for your work on this project and taking the time out of your day to deal with my report!

Forgot to mention this here, but premium content has been playable since eaef6ed if you're logged in with a premium account.
