I have to say that Wicked was one of the last musicals where I liked the music before I saw the show. Given its album sales, I think many would agree. It isn't necessary to see the show to enjoy the music.
Growing up I bought and loved a lot of OBCRs of shows I hadn't seen. That's not often true anymore. I've regretted purchases of many recent hit shows I haven't seen. (I don't live in NYC, you do what you can.) I'm sure the songs work in the context of the show, but they don't really stand alone all that well.
I haven't seen Matilda and have only heard great things, but none of the songs I've heard have motivated me to download the album.
