Embassy of Time

I'm kind of trying to figure out how one would best promote music on a website (as the title says). I'm trying to help a friend out, and just placing the tunes on a webpage for download or playing just seems meh. Are there any cool tricks, or perhaps even some cool websites, that will make a music promotion look a bit more interesting? I'm even up for a website that just -shows- a good idea, maybe it can inspire me to code something for him...
