Yes. JRiver tells me that, at the moment, I have 222.9 days of recordings if I listen 24 hours a day. Despite that, I have almost 2000 discs yet to be ripped and I keep buying more discs and files. (Does this comment belong in the obsession thread?)
I don't know if I am getting my information the same way, but if I just point to albums then at the bottom of the screen it tells me how may files I have (presumably, files include cover art and cue files and not just individual tracks) and it reads 1.91 years.
