Indeed. I've listened to music from over 2500 different albums on Spotify (thank you, Last.fm). Back in the days of $15 albums and no way to buy individual songs this would have cost me $37,500. With $1 track purchases, things get a little more reasonable. I've listened to around 10000 distinct tracks, so now I'm only spending 80 years worth of Spotify premium for the music I've consumed in 2-3 years on Spotify.

Of course, this ignores the fact that there's no way I could have discovered all the music I listen to without Spotify. Even if I knew of all the artists I listen to on Spotify, I could never possibly have found all their music in physical form. And if I had to purchase all the music I listened to separately, I never would have been willing to explore so much.
