I've been finding that FAB Chart quite fun to follow.

Where's that Pop-i(?) chart which you mentioned, JK? I might check it out.
I used to always follow the BBC singles chart, but over the last few years it became a bit stale. However, it did seem to be picking up slightly just before they axed TOTP. I wonder why the BBC put such clueless people in charge of that show?
