Most of Zooropa is definitely underrated. The only songs I would omit from that list is Stay and The First Time, simply because those have become somewhat regular live occurrences.
But the rest of Zooropa is somewhat of an interesting album for me. Most of my playlists don't have songs from that album, but there are some days when I am craving Lemon and have to listen to on repeat for an hour. Then I won't listen to Lemon again for about a month. Hurray for random intense cravings for Zooropa.
