It's not worthy of a second topic, but I just had a total geek out due to music.
So, as a kid, I was a fan of Letters to Cleo (I grew up in the 90s, but honestly, I still like them). I had never played sonic heroes. But when I was listening to the theme of Amy's team, I swore the voice was Kay Hanley from Letters to Cleo. Turns out that it is. Jun Senoue from Crush 40/Sega approached her for a collaboration.
Letters to Cleo + Crush 40 + Sega = 90s Nostalgia Attack. I honestly love that SEGA always had popular music as their soundtracks. It dates the games. But the nostalgia is amazing. Sonic Boom (Sonic CD opening) by Spencer Nilsen is pure 90s. But that makes it much better.
This was almost as good as finding out that Uncle Phil from Fresh Prince did the voice of Shedder in Teenage Mutant Ninja Turtles.
