Watched my friend Mike try to write songs for his band last year. He kept cranking out these tunes that all felt the same, lol. He was so stuck on the same few chords he found online that everything sounded flat. It totally reminds me of these park bands, like they all found the same beginner guitar tutorial and just ran with it. Mike finally got bored of his own stuff and learned some weird jazz chord from his dad. It honestly broke the whole cycle for him.
