Can you add song:

This link will take you to some information about getting it added to the index:
http://www.chordie.com/forum/viewtopic.php?id=4613

The song has to be hosted somewhere on the Web, and in Chord-Pro (Chopro) format.  So copy the url and include it in your request so it can be "vetted" and possibly added to the database during the next update cycle.  Some info is in the FAQ on the Resources tab at the top of the homepage, and a quick look around the About Chordie section will reveal a few conversations on the topic as well.
Oh, and a Hearty Welcome to Chordie!  You might want to wander down to the Chat Corner section and introduce yourself to the Community, you'll find us a friendly bunch.
