Many thanks to Daniel Gardiner who got in touch to provide me with album chart data for the period from 2001-2003 where I only had the top 20. I have now imported the data and this led to the creation of 20 artists and 290 albums which had not previously been featured on the site. Hopefully this should reduce the number of questions I get from people who complain that an album is missing from the site! If anyone else has any more data I would be very glad to receive it. The next step is to add cover art for these new albums.
