I have everything (=ripped CDs and/or downloads) on my laptop. The rest of my family has very different tastes or schedules, and my stereo set up kinda sucks, so consumption via headphones is best. I have separate slightly higher quality headphones for enjoying music, and a different headset for internet meetings and such, so it's fine.
I have not considered using cloud storage yet. Basically because A) they still fit into my hard drive, B) I'm rather old-fashioned. My purchases used to be CDs exclusively, but that changed at the beginning of the pandemic, and my meager Bandcamp collection just reached the 100 album mark. I still purchase also CDs (by mail), if I want to support the artist a bit more. Or, simply because I also want to listen to it while driving. In other words, a subset of my CDs is in the glove compartment of my car. True, most music cannot be properly enjoyed with the car/traffic noise in the background. I guess it would be possible to bring music on a stick to my car also, but I haven't bothered figuring out how exactly that would happen.
I never use my smartphone for music. If travelling or at work, I have my laptop with me.
