If you consider mainline Pulp to be Jarvis, Russell, Steve, Candida, Nick and Mark. Then solo Jarvis albums are more Pulp than the It album as they have Jarvis and Steve rather than just Jarvis. That's my argument anyway!
Wow what a mess. We can't start including Jarvis songs, thats not Pulp. There are more than enough original Pulp songs to choose from.
There is no criteria for matching songs, as long as they are Pulp. Just keep it realistic. Matching Common people with Silence (which is only a demo anyway) just to get Common People an easy point will just end up making the results less accurate. I'm keeping a record of all of these so try to make the effort so it actually means something.
