My Chemical Romance
The other day I was looking at the audioscrobbler (the core, the data supply of last.fm) web services for interesting feeds and I saw the week chart feeds. I noticed that they provide a list of all available weeks and quickly realized that you could combine this with the Top50 feed to reconstruct older Top50's. Just subtract an artists play count from next week's total play count and you have the current total play count.
