I love about half of "Combat Rock" and "Sandanista" both, but the other half... yeesh. "Sandanista" is the most problematic because there's a good ten songs on that album that I actively don't want to listen to; they needed an editor so bad. I really think they put literally everything they recorded at that time on the album. The lesser portion of "Combat Rock" is just kind of boring, not actually bad.
Interesting that you'd take those two over "London Calling" though. That album is classic for a reason.
