I currently have 18,875 songs (from Hoster create song book). Yes, there are many duplicates but my "book" does not have a single duplicate (unless it is by a different artist). My book is a 3" D ring binder and I have my songs listed as Artist and Song. I use Kinko to print my books and I take 8 of them to my shows. I OWN every single song in my show and I have a code that I live by: I will not offer a song to be played unless I own it. Sure this is expensive but then this is a business as well. I report every dime I get to the IRS so I don't have to "look over my shoulder" ever. I too have had people "give" me the original disks and then I consider them mine. There are cut-rate KJ's that have so many "hot" songs who are killing the KJ business. I have a great time doing shows and really enjoy singing. (I have a rule that if there are more than 5 singers in the rotation then I do not sing.) On slow days I have a blast.
