Android mp3 downloader source code

Hi all I need a brand new android mp3 downloader source code, so I need an experienced android app developer to build it. I need a completely new source code, instead of the existing and modified source code which is commonly sold in codecanyon or in chupamobile. The source code is also not made with mp3 sdk from mp3sdk.com. The app I need is based on famous mp3skull mp3 download, which you can find there; [login to view URL] Or may be you can make better than mp3skull app above, it will be great! The app has to have the ability to search the web for mp3 files, let you download it, and show the progress of the download. Notify you when the download is finished and let you play preview without downloading. I also need to be able to implement my admob code in the app. The source code also should be easy to customize, like change the text and toolbar color, and easy to change the background image. Thank you. Notes: A successful bidder of this project should have no problems doing this. Should this app receive 5,000 ratings, with the total average rating over "4 stars", a $1,000 bonus will be given to the developer.
