The Wedding Album is rather infamous, as it's basically nothing but her and John saying each other's names for 20 minutes.

Wow, you think they would have gotten bored making that.

I like a lot of her more pop songs, though. Her work on Double Fantasy and Approximately Infinite Universe is well worth checking out.

I have heard her Double Fantasy work, but only the occasional song from Approximately Infinite Universe. I have the problem wherein I dislike her voice, but I think she's a better songwriter than she's usually given credit for.

Yoko pretty much single-handedly turned him into a feminist.

selenak once made a great post detailing John's failing as a feminist, post-Yoko (for example, how badly he continued to treat Cynthia during and after they divorce), but she did have a huge affect on him, and he did do a lot of things he probably wouldn't have done without her. (becoming a househusband, for example).
