Bob Dylan just sold 600 or so songs to Universal for apparently 200 million. Google it for more info.
Do you think he would have made the same money in ten years if he kept his music?
If you were him would you have sold it?
If you are a musician will you pass all your music rights down to your children?

 

Don't know his current situation but he could be dead in 10 years, and likely isn't making money playing live at the moment. At some point, you need to do what you need to do to live your life.

 

Don't even know why I care. To me just sounds like it would be worth more long term than current offer or just more valuable. But yes who knows maybe in future music is worth zero as well.
Too late you sound like these eco-fanatics.
But those are valid points as well.
