@The Real Jdbye, I thought about that and I have blank DVD's and Blurays but honestly after like 90 songs I just listen to it a couple of hundred times toss it out and burn something else or have like 2-3 CD's. Florida here the heat in the car tends to ruin the CD's after like a few months even commercial pressed ones don't last too long.
Nowdays, my Samsung phone holds most my music on a 512gb micro sd. I Bluetooth to my earbuds, BT speaker, or to my car stereo from my phone. I still have a iPod Nano, but have not used in years.
It takes me 3 hours every week to cut my grass, and I have to have music playing, not to mention the noise canceling earbuds, so I don't have to hear that lawnmower noise. I do play iHeart radio often also when get board of my music.
