Sharebar and MP3 upload/Jukebox

Two projects in one here... We would like to have a custom sharebar created for our client's use. Should be liightweight and simple to install should include Likes - Links, Search and other social media concepts. Second part of the project Want an mp3 upload function... it should verify the filetype (for security reasons) and then we will need a flash-type multi-player to display the names (titles) of the audio files.. Client should be able to add/edit titles into a database table.
