Just go to the iTunes store and search "The Worship Initiative"
We would love to give the charts for free, but they are not entirely ours to give. We charge a nominal fee in order to pay the legal copyright holders and process all the necessary paperwork that involves. We are developing printable files for each key of each song and we'll be adding these in the coming weeks.
No. We've priced the monthly membership so affordably that you'll be able to each get your own. It's $10! A membership gives you access to everything on the site.
We have great tees (and other WI things) available at The WI Store.
That would be great. Please do. Thanks!
