Can I get it to show the regular album cover and square format on the lock screen?

So I know Musi runs off YouTube servers, but I don’t like that the lock screen album art is 16x9 and it shows the thumbnail instead of the song’s album cover. I want it to look like I’m listening to music with any other music app, because that’s what Musi is, but it’s difficult to do that when it’s running on YouTube servers. Can I import my library from any other music app?
