Just me who always liked retro stuff as well, then... 

I think they do occasionally just cut out an offending artist/song if it's easy enough - apparently they did this the other month, but then had to shelve the episode last minute because Scott Mills was presenting. They skipped a lot of 1998 (?) completely because Diddy and R Kelly were all over the charts at the same time.Pretty sure they'll avoid the TOTP from around my 18th birthday (February 2004), since Lostprophets were in the top 10 that week...
