Well, in the course of a normal conversation it would be perfectly natural to discuss our musical likes and dislikes. A forum such as this is different from a conversation but still it is an exchange of ideas, and if it doesn't get out of hand and become a slagfest I don't see anything wrong with the thread. It would be kind of one sided if we only discussed music we like all the time. Of course it may be a vain hope that things don't deteriorate....
