No youre bringing stuff up, read back. OP said a cd, not a digital copy. And when you buy a cd, you own a copy not rights. You can't play the CD as part of your election campaign, or make it your eHitler Minecraft theme and publish it on YouTube. There are terms of use by which you must abide. OP said you buy it you own it and you do whatever you want and that is patently false for a CD which is their example not mine.
If you want to talk about digital copies that is different in some ways you describe, but I. No world do you buy a copy of a song and have unlimited permission to do whatever you want
