How to get secret song?

[yau1024]

when I got 3500 credits, I got the song called Hyper Pressure.
I am having 4500 credits and I still cannot get another new secret song.
Do I need to get more credits or do something else?

Also, could anyone post all the secret song at here?Please!
Because I cannot find any site for secret song.
