I found it interesting that they compare CD burning software and a music player. In 2017 I am not sure how relevant these software were...

I myself haven't used CDs for around 10 years now. And apart from my love of ncmpp, I would also suppose the majority of desktop users would listen to music from a streamer service.

I'd rather had a look on the Settings / configuration dialogs, file pickers (as it's been mentioned already) and other stuff that are relevant (and were relevant in 2017)
