Add Lyricsplus data base

[HAMBURPIZZA34]

I just started using this music app after switching from Metrolist (since it became obsolete for me the app no have new content), and I noticed that its lyrics synchronized perfectly, featuring a word-by-word format that makes it much easier to understand if you want to create your own lyrics. Therefore, I propose adding Lyricsplus as a lyrics provider. It's the database my previous player used, and it nailed every single song, always fetching the word-by-word version unlike what happens now. I hope you can look into this, thank you!
