When I had a kid, we had a cassette player and we used to play music from a cassette player. When I was in my teens. In my teens, I bought a USB device that also had an inbuilt music player. Then one day I bought an iPod. I was using iPod until I bought a smartphone. These days I listen to music mostly on my phone. Sometimes, especially when I am using a computer, I also play music on my computer.
