This caught my attention. It's a bit of Ricky Gervais on Radio 4 picking his favourite tunes. The clip I've linked to there is where he chooses a Neil Young tune. That's surely a good thing. Here's a list of things which, if you like them, makes me think well of you as a person:
Winnie The Pooh.
My old talkshow on Hallam FM, particularly if you know the names of the VIP callers.
Bagpuss, particularly if you've got a favourite episode.
Chris Morris and to a lesser extent Steve Coogan, simply because everyone likes Alan Partridge.
The Beatles, I mean they've got to really f#cking love them. Not just think they're ok. Everyone thinks they're ok.
It's not an exhustive list but you get the idea. It's odd but I really do like people without question if they drop the right stuff into conversation. I'm quite simplistic in that respect.
