AEP is a measure of how diverse your music tastes are, based on the top 50 artists in your Last.fm profile. It was invented by C26000 and you can find full details about how it is computed here. AEP is a number, usually below 5. Roughly speaking, if it is greater than 4 you have very diverse taste in music, if it greater than 3 then you have fairly diverse taste in music. At the other end of the scale, if it is less that 0, you are probably an obsessive fan of your top artist. If it less than -10, you are probably a fake top fan. Depending on which end of the scale you are, you can join either the We Don't Have Exponential Profiles or the We Have Exponential Profiles group.
