Whether it's Metallica or whomever performs the one song for Iron Maiden....I really hope they play "Wasted Years." That's their best song in my humble opinion and would show off the melodic dynamic that Iron Maiden's songwriting exudes!
As I mentioned before, cast recordings of musical revivals are also perfectly fine for nominations since there are notable revivals that became iconic than the original productions.
Here are some notable revival cast recordings to recommend:
Cabaret (1998 Cast Recording)
Chicago (1997 Cast Recording)
Sweeney Todd (either the 2005 or 2022 productions)
Into the Woods (either the 2002 or 2022 productions)
Assassins (either the original off-Broadway production or the 2003 revival)
West Side Story (2009 Cast Recording)
Pippin (2013 Cast Recording)
Hedwig & The Angry Inch (2014 Cast Recording)
The Color Purple (2016 Cast Recording)
Falsettos (2016 Cast Recording) (Fun Fact: The Revival Cast just had a 10 year reunion concert a couple weeks ago)
Oklahoma! (2019 Cast Recording)
Sunset Blvd. (2025 Cast Recording)
It's worth noting that both P!nk and Shakira have been nominated for the 2027 Songwriters Hall of Fame.
This definitely reinforces my suspicion that these industry awards share a lot of the same committee members, especially since the Songwriters Hall of Fame seems even more like an industry circle jerk than the Rock & Roll Hall of Fame.
P!nk's recent negative publicity clearly hasn't hurt her standing within the industry or her chances of being nominated for the Songwriters Hall of Fame. I could easily see her making it back onto the Rock Hall ballot soon. She really does seem to be highly valued by certain influential people within the music industry.
