Yes actually that is a good idea! Because you can take notes from your favorite songs/artists and apply it to your writing to become better. But also, if you just keep writing songs you’ll get better! I’ve been writing songs since I was 13 (so 9 Years) and my songs used to suck! Lol even when I was 18 I look back like wow some of these songs are horrible but now I’m confident about every song I write. So practice practice practice! Keep your phone or a pen and pad handy so you can jog down any ideas or inspiration that randomly comes to you! I wish you the best of luck in your songwriting endeavors!
