honestly, I just sing along when I’m in the car or when I’m playing them at home- sometimes if I’m on my computer computer, I’ll pull up the lyrics so it’s a little bit easier to follow along with. I don’t think it’s a big issue though if you can’t memorize the lyrics, you’re not less of a fan if you can’t sing along. Concert culture got a little toxic with that mindset of “you need to sing along / know all the lyrics” it’s not a huge deal in my opinion
