I'm looking for a theme

[Simpatinate]

I'm in a place where I can't have a phone but I can have an mp3 player. Is there a theme app that hides my os and makes it look like an mp3 os?

I think you could install Rockbox, then a Rockbox theme. Rockbox Themes - Frontpage

Or ssLauncher pretty much let you configure any look you want.
