I find that odd critera for a favourite-album-ever list. I tend to default to Dark Side of the Moon because I first fell in love with it 25 years ago and my opinion hasn't changed since then. I might consider that Battles are helping music evolve, but imagine I probably won't play Gloss Drop that often in 25 years' time, but will still be listening to Dark Side of the Moon.
You're right.. I just really like new things.
A lot of metal especially (Death, Metallica, Iron Maiden, etc) that is considered classic I can't even get into because it just sounds outdated to me. I'm sure they were important to the scene, but newer bands are just coming up with more interesting riffs IMO. I suppose they're not really comparable to Pink Floyd though who are definitely timeless.
I'm quite certain I'll still be listening to the albums I mentioned when I'm older.. I guess nostalgia plays a role here. :shrug:
