Music Playing App by Voice Recognizing

50% of total budget will be released after checking the successful demo. Without showing me the demo apk, please don't even bid or ask me to create any milestone. I need an Android app designed and built in which users will be having a feature of listening music by searching manually or only by calling the name of the song on app feature. It shud be faster and quickest. User will just speak the name of the song and app will play the song instantly. User can also search the song by typing its name or keyword. Database and admin panel will be created by developer only within this budget only.
