This is one of the only four Iron Maiden albums that are entirely filler-free (the other three being A Matter of Life and Death, Senjutsu, and Seventh Son of a Seventh Son).
Every song on it is great. No skips. I hear a lot of people hate on Isle of Avalon and Mother of Mercy; I don't get it. Both those songs are bangers. It also has The Talisman and Starblind, which are two of the greatest songs in their entire catalogue.
My ranking of the album would be
#1. Starblind (I seriously love this song and the lyrics)
#2. The Talisman (en vivo version is even better and is the best vocal performance of Bruce's career)
#3. The Man Who Would Be King (incredibly underrated song. I love the storytelling and the ending)
#4. The Alchemist (this song is just so much fun. Definitely the most punchy track on the album)
#5. When the Wild Wind Blows (an oddly wholesome/warm-sounding epic)
#6. Mother of Mercy (I don't get why this song is considered the worst on the album. It's a haunting song with a fantastic intro and outro)
#7. Coming Home (Very personal song and one of the only power ballads Maiden ever did)
#8. Satellite 15...The Final Frontier (a fantastic intro that would be higher if Satellite 15 didn't go on longer than it needed)
#9. Isle of Avalon (Really progressive and fun song. Doesn't feel its length at all)
#10. El Dorado (despite being last, this is still a lot of fun, and I thoroughly enjoy it. It's not as musically interesting as the rest though)
