Jun Senoue on The Best of Sonic the Hedgehog Part 2: True Colors:

Believe in Myself (SA2 Version)

Concentrating the meaning—no alteration in the message nature in the theme song of a character—on anything, we newly finalized the composition on the decided musicality by character while utilizing the same lyrics in Sonic Adventure and Sonic Adventure 2. I like the lyrics of Tails’s theme song and I am extremely happy that many fans say they like it, but personally, I am more pleased with this version that has become more rhythmic.
