I still just keep an offline existing music collection that I update every once in a while. remove stuff I don't really listen to anymore, add stuff I'm listening to now (through various sources, youtube or buying an album download, etc)
this whole streaming thing is just a nightmare through and through and being tied to an internet connection constantly is a bit stressful. especially when out and about.
I highly recommend a personal library if its a feasible spacewise for your devices.
I wonder if tabletop was popular before d&d brought it to the mainstream.
