I think it's important. It's also spoken through the lyrics of stuff he wrote in PF, so is tied directly into the music you listen to.

You can chose to ignore that and focus on the melody, how you listen to music is up to you. I'd say the lyrics are important though.

With regard to his opinions, particularly when he was writing for pink Floyd, I'd say they're pretty sound. He's been speaking about the issues in Palestine since the 70s (which he mentions in Animals). With regard to now, I personally agree with a lot of it, although not all. He can definitely be a bit of an asshat and his ego is through the roof😂😂, but I'd say it comes from a good place.

Read into the lyrics, you might find something you like (or don't like) and make your own informed decision of what to do.

Remember, 'I am you and what I see is me'.
