My favorite Kamen Rider Songs are "Amazon Rider Is Here" by Masato Shimon (Kamen Rider Amazon; 1974) for the Showa Era and "Anything Goes!" by Maki Ouguro (Kamen Rider OOO; 2011) for the Heisei Era.

If I had to pick only one... hmm... Let's just say I'm "not allowed to say no"

but Faiz and Ryuki come close.
