I need simple tab based material design music app. Tabs are: Serach, Downloaded mp3, Downloaded Video

1) Search tab: Here user will enter e keyword and app will search API's and give him search result. User can play, download as mp3 or mp4 the search result.
2) Downloaded mp3 tab: here user will see list of downloaded mp3 files nicely ordered. User can search by typing a letter on search bar on top. By clicking on item user can play, delete or add to play list the selected item. when clicking on item small music player appears from bottom with prev, next, playstore, repeat, shiffle buttons. When playing music player widget should appear at notification bar also with tumbnail, play, stop, next, ptev and close button.

4) Downloaded mp4 tab: same as mp3 tab but user will play video.

5) User should be able to generate Playlist for mp3 and mp4 files separately. User can add or delete from play list.

App should be well coded and optimized to handle faster search if there will be many items on download list.

All api's will be provided by me.
