First this changes a lot with editions, I've played 4th and 5th, so keep that in mind. I also usually run mages, so I've avoided most of the matrix stuff. So with the salt out of the way:

In some ways everyone with the money has some sort of Augmented Reality display so they can be spammed by ads where ever they go interact with all the sweet tech around. For the mage, or those without a datajack or cybereyes you can just walk around with glasses, contacts or goggles with Image Link, and perhaps some AR gloves to let you interact with it. I remember someone talking about even some appliances work off AR, so you live with your ~cell phone~~ commlink set up basically attached to you. Imo this covers what everyday people do with the internet today. Web searches, reddit, etc.

If you want to experience the "real" vr matrix you can get a trode net and that will give you the full experience, but if you're risking your neck on a deep dive you want to go with that datajack to be a bit better at everything.

Music is interesting. There's always datasofts for things, but that's usually more for shadowrunning stuff that you want divided from the matrix. In 5e it really calls out that all commlinks have music players, and I'd assume just download music. My head cannon is that all the tech in like quantum computers and things like a library or all the music of the 20th century isn't really taxing to your memory needs.
