MSEP is my favorite parade mostly for the memories it brings back. I first saw it back in 1980 with my family at WDW. My Mother absolutely loved it as well as the music, she even bought the soundtrack and I believe on vinyl. Whenever I hear the music from that parade it always reminds me of watching Michael Iceberg play at the Tomorrowland Terrace.

While Optimus may be the most well known Prime, Solus Prime is my favorite.
