Yes, it’s probably a very “2007 question”. But interestingly, my personal stereo use has gone the other way. Prior to the tinnitus situation, I did at the very least bring my old trusted iPod along for long travels. But now I don’t even do that. And I’ve never used my phone for music listening.
I’m guessing the Quboz thing means that you have to be connected to WiFi, though? You don’t have any music on your phone for situations where there’s no coverage?
