The short answer - I’m kinda neat about these things.
The long answer - Since the last.fm design revamp in 2007, I noticed around 1,300 artists in my library. Around 300 had less than 3 plays. I remembered most of their names, but not the actual music or melodies. I rushed to erase one-hit-wonders and mis-tagged artists, wondering how much highly acclaimed artistic material (read:crap) one could come across. So I googled some researches on how many artists, songs or melodies a person can remember and did not find any supporting evidence. I estimate an average person can recall around…
