Yeah that "warmer" sound @williamb29 mentioned is totally a thing. My buddy just saved his dad's old amp with some cleaner, he was blown away by how much better it sounded than his new bluetooth speaker.

Honestly, you broke the law the second you scanned and sent those files. Copyright doesn't care if it's for one friend or a hundred, you shared work without permission. Those writers and artists from the 70s might not see a direct dime, but it devalues their art and the whole industry. That friend could easily forward your email, and now it's out there forever. Feeling bad is your conscience telling you this was a mistake, not a gray area. You had a better option, like pointing your buddy to a digital service that pays for licenses.

Hold up, taking rocks from a geological site is usually against the rules. Those areas are protected so everyone can enjoy them and scientists can study them. If you remove that quartz, you're damaging the site for others. It's not worth the risk of a fine or trouble.

Not me, I always underorder and regret it.

My old gym got me for $19.99 a month for like six months after I moved away... I just kept seeing it and thinking it was some other app subscription. Finally looked it up and felt so dumb. Had to call and argue to get half of it back.
