Please send your song to webmaster@lankasongbook.com. You can either write your song using 'sumihiri' notation, or using 'Singlish', or simply scan a handwritten song and attach to your mail. (The last method is preferred, but any method is actually ok.)
Please don't forget to include your name (it will be displayed as the one who submitted the song), artist's name, and if you know the lyricist's and mucisian's names.
I cannot guarantee that the song will be included as, for now, I tend to include only the songs that I like. Once I have developed the mechanism to maintain personal collection of songs for the users, I will include all kinds of songs - not just the ones that I like, but that is going to take some more time.
