Is it normal i don’t really like led zeppelin outside of stairway to heaven?

It may be because that song set the bar too high, but imho all their other stuff really isn’t that good by comparison. I’m not usually one to pick favorites, but I usually say Stairway to Heaven is my favorite song when asked, because it really is powerful, but maybe it raised my expectations for them. And you would think it’d be a perfect match for me. I love 60s and 70s Rock, and I’m also a big LOTR fan which they reference a lot, but I just could never get that much into their music. It’s not like I hate it, but it’s like if you marathoned a movie series and the first installment you liked so much that the rest just don’t seem very good by comparison, even if they are pretty good.
