Introdu-sing AudioSiren

I am just posting music, that's all.
Feel free to follow me if you want.

The starting conditions of something
greatly impact the end result,
you know?

My music holds a secret.
What secret? It's a key, of course.

I will just be posting music and assume anyone that likes music isn't as much a fan of reading as listening. So this is about as much reading as you will be doing here other than some lyrics in the video. I wonder though, can you read between the lines?
