Count me in as well among those who aren't able to come up with long musical lists, I could at best do so with a specific album, but not with an entire carrer. Especially with Iron Maiden, my favorite band that I listen since 1995, for which I wouldn't know how to begin to compare the songs I've heard over all these years. How do I rate The Trooper, a song that I listen to since 25 years, against Empire of the Clouds? how do a 18 minutes long piano ballad ranks above or below a song I heard a gazillion times and that I know inside out to the point that I don't even listen to it anymore, except for live shows, which is a 5 minutes galopping rocker anyway?
And it's not like I'm not without my quirks. For example when I go to work I listen to compilations created as a setlist. I even pick an intro - I fool around with classical music maybe used by the real band or I make it up fooling around with free sound effects I find on Youtube) and I do encores, to the point that I calculate some additional time to pause the playlist before the encore starts. And I carefully pace them so that I can have my favorite songs in the moments where I can't do other stuff on the subway like reading, for example when I'm waiting a commute with another line, that's when I want to make sure I listen to a song I particulary like. And I even change "setlists" from "tour to tour", when new albums come out. In 2017 I made a 20 years anniversary compilation / setlist for Bruce Dickinson's Accident of Birth, and I didn't include any song off Chemical Wedding except for a b-side. Why? because I already knew that in 2018 I would have made a 20 years anniversary compilation for that album, and that I would have listened to it in full. Not even Mike Portnoy thinks that far ahead with the real setlists he creates.
But yet I wouldn't know where to begin to determine which is my 17th favorite song and which is my 21st. Not by myself however, I should do a giant league tornament like Destiny of Chaos does to find out probably
Those who are able, I can however understand the fun that it brings to have such solid bases on which to build around discussions about music
