Once your collection is built, thirty years down the line, you'll add less than five CDs per year. With streaming however, you'll end up paying a whole lot more than $5000 for the next 30 years, thanks to inflation. If you started this journey at 20 years old, you'll only be 80 after 60 years of streaming, but you might get to live until 110 and get to pay for yet another 30 years, which you may not be able to afford at that point in your life anymore.
