Lyrics Gaps lets you choose a song and the language you want it sung in and then gives you the option of seeing/hearing it in different modes — karaoke, beginner, intermediate, expert. Apart from karaoke mode, you’re then shown a YouTube video of the singer, along with the lyrics on the side including blanks (fill-in-the-gap).

I especially like the beginner mode, which provides several options to chose to complete the sentences. The higher levels don’t give any hints.

I’m adding it to The Best — And Easiest — Ways To Use YouTube If, Like Us, Only Teachers Have Access To It.
