Ever wanted to see the lyrics of music videos that you are watching on the Youtube? If yes then this functionality is provided by using certain scripts.
How this works?
You need 2 things to enable the lyrics dialog; one is a firefox extension and other a Userscript that does the job for you. The only precondition being the music video should contain the name of the song in the title as the title of the video will be searched in the music database in the web.
1. Install the Greasemonkey extension of the Firefox browser as using this plug-in we will be able to make some changes in the browser.
2. Install the Userscript that adds the Lyrics to Youtube.
The Greasemonkey script is responsible for enabling the lyric dialog in the Youtube videos and the Userscript actually finds the lyrics to display from the database.
