This is a very useful tool for anyone looking for a simple and straightforward way to learn popular cover tunes. I've used the Ultimate Guitar website for years to get the chords to cover tunes I could use to fill out my sets, but I always found the clunky interface and tiny print on their site cumbersome to deal with. Mychordbook is a lot easier to work with and far easier to read. I wish this was around back when I was gigging. This is definitely a steal of a deal if you play guitar, uke, or piano. Five tacos from me.
