I'm guessing there aren't a ton of worship leaders on this board but it's worth a shot. Anyone use Spotify to plan their worship services at church? I create a master playlist to keep track of all the songs that we currently rotate and then create a "set list" for each week so I can listen to the songs over and over again. I'm also a big time user of Planning Center Online to build the worship services, schedule people, etc. - which has Spotify integrated within the system.
