[Geoff Bacon]

Everything goes in to "Songs" - this is the master list of what is available

Create separate collections for your different categories.

Remember that a song can be in more than one collection.

You can use a filter to restrict displayed songs a to particular collection (or collections)
 
Setlist are also available but that is usually for something like a gig where you want to play songs in a particular order.

Cheers
Geoff
