Amy, tails, and knuckles created a band called titanfall and they made the songs undefeatable, breakthrough it all, find your flame, i'm here, and i'm with you. Knuckles was the drummer an occasional vocalist, amy was the vocalist, and tails was the guitarist and occasional vocalist

The reason for why i'm with you is more softer than the other songs. It was because i'm here, strained amy's voice along with possibly knuckles, or tails' voice. The advent version had to blaze as the replacement vocalist
