I have played drums for years, little bit of piano and the guitar on and off for 20 years. You will find out that most songs 1: Are mostly variations of about 5-6 chords. 2: Any new song is a variation of maybe 3-4 chords. 3. Its actually disappointing to find out that this is all there is too many of songs from guitar drivin bands (Greenday, Offspring, ETC). 4. That to actually play the other small percentage of songs that aren't easy will take you a few years developing your abilities. Which leads you back to 2 and why you will find endless youtube videos of others playing these songs.
