iPod Radio/Podcast/Music - Player/App

I need a "radio-a-like" application which can stream music, change cover art each time a new track is played and give URL links and music infor (e.g.: where to buy songs or concert tickets). The application should be able to play both audio and display pictures and possibly Mp4 videos and have several sections such as "On Air" (would be the main page), "PodCast Dowload" (would be a section containing many PodCasts to download", "Pictures" (would be a gallery of pictures), "Message" (to send a message to a specific email address). In terms of style i want a very similar look to the following"Radio Deejay" application available at this address: [login to view URL];mt=8 Timeframe for delivery: I need to have this up and running asap.
