A few points:
-
It’s totally fine to pursue learning power chord songs at the expense of other things for awhile. Power chords help build your hand strength for things like the F barre chord, plus it makes you happy, which is what this is really all about.
-
If you spend the next few months doing nothing but play power chord songs on your electric, then it might take a few practice sessions to get comfortable with your acoustic again and to remember the “acoustic” songs you were playing, but that’s OK. Everything we practice has a synergistic effect; time spent with your hands on the instrument is the most important thing.
-
Although your overall skills development may progress faster if you balance the two (50% on learning power chord songs, 50% on other practice items), who cares? As long as you’re not wasting your time working on skills that are way beyond your current capabilities (such as practicing sweep arpeggios when you still can’t strum the old Faithfull pattern), anything you do on your guitar will make you a better player.
YMMV
