Youngsters these days.

I prefer my 4000 or so lp's, but my son streams, exclusively.  I bought him great earbuds and a portable dac for his computer, he's good. he told me a "dad joke": 
"My neighbors listen to good music.  Whether they want to or not."

Jim, not that I've any children or grandchildren.....but you might remind Snookems that:

1)  You made half of his parents a reality.
2)  When you got irritated, they called you 'Sir'.
3)  You and the 'other Boomers' contributed to making their 'lifestyle'  possible....partly by not holding said parent under until the bubbles stopped...
4)  How long can you hold your breath?

We didn't have to 'get involved', but we've learned an amazing amount by just watching....and avoiding 'babysitting'.

"Well....Uncle Jerry said that if I put Bach on and ran it backwards, there's demonic messages...."

I've got a bit of most of the formats....including some transcription discs bought from Habitat, just for fun...

Just play what you want. You can'rt take it with you.

If you really are thinking about buying a new CD player could i suggest that you opt for one that is capable of playing SACDs? SACD sounds so good that it is now my first choice when i am looking for a recording of a particular piece of music.
Remember, just as when we were their age, young people tend to do what they see their friends doing. So because their friends use their phones to do absolutely everything, it feels natural for them to use their phones to listen to music too. However, it is quite easy to convince anyone who is really interested in music that the sound quality can be improved if you are willing to experiment with some decent hifi equipment. To that end, I have made a USB connection available on my hifi so that when my children's friends come to visit they can simply connect  their iPhone to the USB connection and their music plays through my big speakers. Some of the more adventurous have even tried playing a vinyl record or CD and they have commented that they do hear a noticeable improvement in the sound quality, so i think i am developing some incipient converts. I cannot compete with the portability of a mobile phone though. 

I’m a CD guy so I shouldn’t have any problem with digital...and I don’t. Havn’t streamed yet but my kid does and its fine...except for the music itself. I’m not much for pop music unless in the car. At home, it’s classical and other period music, most sonatas, some blues, some folk, some alternatve rock, some classic rock and lastly, some Swedish heavy rock...ah, Sabaton..among others.

I plan to stream shortly and use bluetooth but I still enjoy finding CDs I like. The lastest acquisition is Brahms Complete variations played by Wolfram Schmitt-Leonardy...very, very nice. On a brilliantclassics label import...try finding that streamed.
I don’t do vinyl except to resell to feed the hobby. Equipment used Hegel h160, Focal 807W, Marantz 6006 as transport. Cheap bluray for movies.

Vinyl? If I easily found what I liked, maybe I would, but I’ve no desire. Does it sound better? Not at the volumes I typically play at, which is low to moderate. If I want snap, crackle, pop...I eat cereal. Though, I remember that Hotel California sounded better on vinyl. That could be that I was younger with better hearing, or I romanticize that it did or perhaps it was mixed to sound better on vinyl. If I listed to more classic rock at home, I would seriously consider vinyl.

So, like the above have stated, streaming is fine when traveling, for home if in higher resolution. CDs are generally cheap. Leaving vinyl for those who have deep pockets and hipsters. Part of the fun is physically searching for finds. It’s not an adventure flipping through a website.

Lastly, it’s OK to be an OK Boomer...OK hipster?

Youth, like CDs...here one day, gone the next.
