Android app - repost

Hi I need an app to play music when I'm talking to someone on the phone, it must be played in a way that both of us can hear while we are talking, like it's playing in background. and not be played from speakers, just from hearing speaker. features: - when the phone rings or I call someone, the app will be activated and a message will pop up that asks "do you want to play music" - there must be a music list, and musics can be selectable from sd card. - settings (background music volume, ask when ringing to play) - and also beautifully nice interface. thanks
