I'm not bored of em yet, but who's to say what will happen in the future? I went back to Stoner Witch last week and I think I enjoyed it even more than back when it was the only Melvins album I had. Now I have, er, many many albums. I think they've remained distinctive whilst evolving and changing a lot throughout the years and that's cool. I haven't really listened to _that_ many bands as intently to find out about them though, they could all be like that for all I know! The more you know, the less you think you know.
Change is good though! It's healthy. Rotation of the record collection is fine by me.
