Listening to or even obtaining non-free/label music legally is now easier than ever with online-platforms and services like YouTube and Deezer where open-source software can download the source using their published API (even if it's against their TOS).
I don't see the need to actually pirate, illegally copy music, torrent, or ripping music off of disks anymore.

Of-course if you like a particular song you're listening to you should always consider supporting the artist regardless, regardless if you can get it for free.
