This is excellent advice.Thank you for pointing that out!
To the OP- there is no race, no timetable. Learning about music, and how to express yourself clearly with it is a lifelong journey. So learn those songs you want to know. Write down how long it takes you to get them close, and then how much longer it takes to get them perfect. Then go back and work on your chord theory (just triads and 7 chords for now), and then see if it helps you learn the next batch of songs faster.
The thing about theory is that, once you tie it into songs and how it sounds, it makes learning new songs, or writing your own parts for brand new songs, much easier. Not having to fumble over potential note choices, or being able to really tell what a drummer is doing rhythmically, will help your creativity, your flow, your groove- it will help your playing. But take it as it comes. Like a previous poster said, it's not a sandwich that needs to be finished in one sitting, and there really is a bunch of stuff in there.
Never conclude that you've finished learning. You can get to the stage where you've learned "enough" - but there's always more, and it's never a waste of your time.
U fail at sarcazm!!
