A few years ago some mates of mine decided that if their girlfriends / wives were going to form a book club as a regular feature of their social calendar, the guys should do something similar.
The blokey equivalent was obvious, particularly as several of us are music anoraks: a Record club; a long-running membership (give or take a few chaps who've retired due to lack of time or conversely been co-opted in to swell the ranks), who take it in turns to pick 2 or 3 albums a month.
Prior listening is highly desirable, the albums are played in full at the meet-up and opinions are voiced and scores out of 5 awarded (then tactfully forgotten).
Record Club has passed its 8th anniversary which is rather amazing when I think about it - no friendships have been damaged (as far as I know), no fist-fights have broken out. A couple of the guys organise a "best of" compilation CD prepared in advance of our Christmas curry night and from the year's selection we vote for Best New Album (released within the last 2 years), Best Old Album and... Worst Album (for which there is usually hot competition).
Oh, and the first (unwritten) rule of Record Club is: no compilations.
The second rule (probably) is: no double albums (even if an original vinyl double has been released on single CD).
The third rule of Record Club is: no soundtrack albums unless the music was specifically written for it.
The fourth rule of Record Club is: no live albums (because they are almost always a kind of compilation).
