Yeah most of those ripper sites just give you the audio with a blank thumbnail or some generic logo. Super annoying for playlist aesthetics. If you already have the MP3 file, you could quickly use a tool like https://www.movavi.com/tools/rotate-video/ just to embed artwork from the video screenshot. Not exactly what you asked for but it gets the job done without re-downloading everything.
