GuitarTricks has many incredible resources including theory, techniques, styles, and even videos on how to play songs. If you are a beginner or early intermediate this could be a very helpful resource. The instructors are all reputable and since some of them choose to cover a similar style or technique you have the option to learn the same material but from an instructor who matches better with your learning style. The only drawback is that they do not have much for more advanced players. Customer service is very quick to respond to messages and make all processes quick and simple.
What's the fastest way to learn songs on the guitar? Learn the guitar chord progressions involved! Below, Greeley, CO teacher Andy W. shares a quick refresher lesson and what you'll need to know to play songs by Lorde, Pearl Jam, the Beatles, and more!   For this lesson, you'll learn the specific chords used in one song for each progression.  To play other songs that use the same progression only in other keys, it’ll be important that you have a basic understanding of how Roman nu

Of course, this top-down lecturing is all very abstract without examples. Let me give you the worst case scenario. My school talent show, 2008. Two friends of mine performED an ambitious but utterly inappropriate Metallica cover in front of the other students, their parents and the faculty. It was excruciating. Although the solos (presumably the only thing they had bothered to practice) were technically flawless, the whole song was undone by their terrible rhythm. The timing of the song became displaced, the chords were so badly fingered that it was difficult to hear the riff and consequently the whole performance fell apart. They looked like morons. They had sacrificed learning basic rhythm and paid the price. Make sure you don’t do the same.
The songs are arranged from easy beginners chords and layer up as you go thought the book. but they really work best with the website where Justin plays and teaches you how to play them then adds a few tricks and skills to advance each song too, so try watch all the songs even if you're not too interested in the song because there are gems of wisdom in them all. (I drew the line at Britney spears tho ;)
