This app is just another lyrics app but with a catch! It shows synchronized song lyrics as toast messages.
Unlike other popular lyrics apps that shows lyrics in a pop-up which will interrupt your touch events, toast messages do not interfere with your touch events.
So you can do whatever you want on your phone and also enjoy synced lyrics simultaneously.
You can also manually sync lyrics.
