Streaming (or caching via streaming) - pah. Do I really want yet another cloud service which gathers data on everything I do and everywhere I go? Add to that that I have no control over the quality of the digital music stream.
Give me a CD of the music that I want to listen to (that may not be available on a streaming service, or even for download) and I can choose to rip it to a file format of my choice (MP3 at highest quality with a decent VBR), put the resulting files on my microSD card and pop that in my phone and listen without breaks, adverts, or any other annoying shit. I retain control of what I want to listen to, not some spotty herbert who thinks they have the right to tell me what I should and should not like.
Oh, and if for some reason I want to, I can listen to the uncompressed* CD directly in better quality on my home system, and I have a decent source should I ever need to re-rip for any reason to a different file format.
Me? Grumpy? Never! ;-)
*uncompressed in the sense that it's probably the best quality most people can get. 44.1/16 is (most times) by definition a form of compression compared to an original recording, which, if I get really technical, is a compression of an actual real analogue sound itself.
