I've just been browsing this week's thread. Problem is, I don't know a helluva lot of stuff in there, and I'm sure we're all missing out on new music by just skipping names we don't know because people assume others know them and therefore don't add descriptions.
Could people be bothered to either do an alternative weekly list for those items on their last.fm that are on spotify, and/or marking their spotify listens with a ^ or something, and adding the album name?
Then on a Monday night, we could compile a last.fm weekly spotify playlist to share. I'm not going to offer myself up to do this every week, but I don't mind doing the first attempt.
I realise an awful lot will not be on there. But it's a start?
