Poweramp now has an experimental service provider API for 3rd party music services on their build 862+ beta version. Maybe you would like to see it and try to integrate your services with this software.
If you still don't know Poweramp, it's a music player that has powerful Equalizer and High Quality output engine and will allow you to customise the sound to match your needs.
