Feature description

The first audio/song is downloaded from newpipe, it does not have a cover like the second, which is downloaded from another application.

Also the second audio says the name of the artist "JM Lyrics", which is actually the name of the YouTube channel where I downloaded the song. I don't care much but I mention it.

Sorry if it's not understood, I don't know English, copy and paste directly from a translator.

Why do you want this feature?

I like to see the cover of the song I'm listening to.
