Yeah, UM3 probably has songs we all hate and can live without. Here's my "rather short" list (in no particular order):
Bassile
Carnival Day (like I said before to those certain people, I hate it big time)
Delta 32
Love This Feelin' Zonk Remix
Sunflower Girl
Virtual Insanity
Hot On The Phone (someone kill that Boyjazz group already please)
Danca de Yuka (ditto for Big Idea)
I'm sure there are more but I can't remember them right now.

Carnival Day
Hot on the Phone
Hateful
Himawari
What I'd Say

I hate bag (to freaking hard)
Whatever that black eye peas song is


that's really it bag gets on my nerves cause its so hard.

Hey Mama? It's not that hard-even on Heavy it's only like a 6. Just increase the arrow speed to 2x. (You want hard, do Legend of MAX on Heavy or Giudecca on Oni)

No, its just that I don't like how it sounds. I agree it is not hard.

Hey Mama is a seven. Deserves it too; slow BPM and 16th arrows make a horrible challenging mix.

anyways, my least favorite songs are

"Hot" on the Phone[if you can notice, it says "you think Im a bitch in it, horrible song]
Hateful
Bath of Least Resistance
Hey Mama[badly cut, could of had the radio edit]
Mi Alma
Whip It
Midnight Fraknenstein
Raise Your Hands
The Imperial Carnival
Love This Feelin
Momemt 40
Rainbow Flyer
/The Legend of MAX

I've improved I don't like Ledgend of the max too much and Midnight Frankenstine. I just don't like the song (Midnight Frankenstine)
