Uh, I liked that song were the triplets got that Robotnick blow up thing. The beat was nice. Can't remrmber the ep. name.

I can't remember which episodes exactly, but I remember I liked the one from one of the episodes Knuckles appeared in.

As for the one I didn't like, I think it might've been the last episode.

I've got a special place in my heart for 411, as it was from the first episode I managed to catch. I remember when I first woke up early to check out the newest Sonic show...those were the days.

411 is the only song I remember from that show. o_O

411 has been stuck in my head for the past 3 days and today.

"I'm lookin for someone! Have you got 411? I'm searching everywhere for this special lady..."

Yeah 411 is all I could remember.

someday,the fastest thing alive, we are sonic uderground egyptian version and the rock version.

"Noone is an Island" purely because Knux is adorable in the vid.

Oh and the song is catchy. =D

And for least fav, "the Mobius Song"... *shudder*
(you can tell I pretty much only payed attention to the ones with Knuckles) *shamed*

I've always liked Never Easy, and Part of the Problem.

Aw, the Sonic Underground songs. While they were at times the corniest part of that corny old show, they were still entertaining. I've got several that I remember quite fondly:

No One is an Island
Cosmic Dance
Being a Kid is Cool
Part of the Problem
Liberty Rocks

That's all I can remember for now. I don't recall too many at the moment that I didn't like, but there were a few:

Listen to Your Heart Girl
Fun in the Sun (I think that's the title)

All I can remember at the moment, title wise anyway.
