For me this one is easy- I have been into hifi and music since the 1970's. between LPs, which I never gave up on, CD and cassettes, I have thousands of titles on hand. I started to table in streaming a little over a year ago and took the full plunge in early 2022, with the purchase of a very good dedicated streamer. I have been able to explore new to me music as never before. For the true music enthusiast who is always interested in learned of and about new music, it is amazing. millions of titles at my fingertip, at a cost of under $11/month (yearly Qobuz subscription). Roon isn't a factor as I am more than pleased with the app my streamer works with. I'm approaching 500 new titles just this year alone.
On the other hand, if you are a person that listens to a handful of albums and is not interested in exploring new to you music, it's unnecessary. But for the music lover who is looking to expand what they listen to, it is the ultimate (almost) FM. [free music]
