If i created a greatest hits of Iron Maiden using only one song from each studio album it would probably look like this:-

1. Sanctuary
2. Wrathchild
3. Run To The Hills
4. Revelations
5. Aces High
6. Wasted Years
7. Infinite Dreams
8. Holy Smoke
9. From Here to Eternity
10. Sign Of The Cross
11. The Clansman
12. Ghost of The Navigator
13. Wildest Dreams

wow that probably wouldnt sell at all
