My Google Music App Album Art is all mixed up

[friardave]

I have a bunch of songs on my old Galaxy S4. It's now my music player.A lot of the songs have ludicrous album art and even different band names. For instance, I have a UFO song with Blink182 art and band name. The right song title. How can I make the art and names match the song? It's highly annoying as I have no blink182 music on my phone. This is not on all songs. Just enough to **** me off. Any advice is appreciated.
