One of my biggest regrets in life was axing my old Last.fm account from highschool when I was in college, as I could have had like 15 years of data at this point. But I do have a recently active one from the past few years.
I also have a Top 100 from my own bias. One album per artist, but the ranking takes into consideration their whole body of work. But I also tried to give some weight to newer artists to balance out that issue. But any ways, all these albums slap!
