The first 20 seconds are magical. Unfortunately the song goes a completely different route afterwards. It's not a bad song, but I'm not 100% convinced by what we actually got. Blaze is pretty inconsistent, with the long notes before the choruses being glaring examples. It feels like they tried to tap into the more happy and positive vibes that a lot of early Maiden songs had on the first three albums, but it doesn't really work for me. The verses are fine, the chorus not so much. I like the first half of each chorus but I dislike the second half.
We get a couple of quick and dirty solos, but they don't meaningfully affect my overall opinion of the song. The lyrics and the phrasing aren't doing the song any favors either. In summary I'm going with a 5. It's fine, but nothing more.
