Three of those songs are alternate versions of songs you listed. Two of those songs are covers. Two of those songs are just early versions of songs you listed. Five of those songs were written in the 80's. One of those songs was not even written by the band. That leaves just 19 songs. That's not impressive at all.
1st of all, I only listed songs that are new to us, no matter when originaly written, and really, those alternative mixes (maybe not Yahweh) are almost totaly different songs.
2nd of all, even with 19 songs you have an 11 song LP and a really strong EP (almost a second album, actualy, like Zooropa), that's very good for any band, impressive for U2
