YAYNESS!!!
This Christmas rocked! Although I paid with my own money... hehehe
I found a store that only sells song books! And it had Total Guitar Rock!!! woooo-hoooo! I paid about 21 USD... 63 REAIS... but it's worthy!
That street is musician's paradise: it has at least 3 music stores for block! Then I also bought an eletric tuner!
