Thank you very much. I'm looking forward to understanding all the lyrics. From what i can hear they sound very uplifting and encouraging. Another awesome feature. :) Also, I think the idea of using the same song for illustrating the different styles of voice is brilliant!... It makes it really easy to tell the difference. 
Thanks for producing these excellent classes and class format. I believe i will be a long term customer. There is so much to learn and finally i can stop going to multiple youtube pages and teaching sites. Both with 30 Day Singer and Guitar Tricks.com... both are awesome. 
(i'm looking forward to Piano Tricks .com ;) ) <3 

So glad you're enjoying our lessons, Xie! I do encourage you to subscribe to our YouTube channel as well - lots of new, free content there!
