Okay, so I deleted the plugin and redownloaded it. I'm still having the problem, but as before, it's not all songs. Screenshot links below.
Plugin enabled. http://www.mediafire.com/file/qk9vd8gb81md405/MB2.jpg/file
Musixmatch set up as the primary website to check. http://www.mediafire.com/file/2m3k4jb5n43fns2/MB3.jpg/file
No lyrics found. http://www.mediafire.com/file/goumbav23zg62er/MB1.jpg/file
Lyrics found on Musixmatch when I clicked the Google search option. http://www.mediafire.com/file/gshgfls9o03xoyd/lyric.jpg/file
I hope this is helpful.
