I really like Assertive's Skybound.
Some other's include Disaster, a bonus track from Aviators "EQ 3".
Open Your Eyes- Aviators: Mirrors
ABRAXI 3.0- Nexaka: Rainbow & Rooted
Nitronic Magic- 5Copy: Rainbow & Rooted.
Heroes (Feat. Bronyfied)- Aviators: From All Sides
Needless to say, my favourite is Style and Speed From Skorp!
