I'm not sure what features are not free, I've been a paid member since before those changes took place. I will say to you this. This is more than a music education site, it is a type of church. Alot of saints from different churches, countries, race, and experience come here. From the babe in Christ to Pastors, from beginner musicians to seasoned profesionals. This is our playground, our community, our sanctuary. Consider the membership fee mearly a love offering and you are sowing seed into a ministry as well as your own growth in Christ.
Be blessed
