As you might know a Song Book is now in progress:
Most common bhajans have been already added and more are added every week.
Some have audio and video files on the pages (all those with ♪ sign after the name). See here an example.
If you want to help, look for videos (on youtube.com) or audios (on soundcloud.com) for the songs without any and send us a note.
We'll add it on the website.
