My advice would be to set up a project page for the song on your website. Write about why you think bitcoin is awesome and describe what the music project would be.
Once you have that, you have a good base for everyone to come to learn about the project. I would definitely say set up a crowdfunding project. Kickstarter is an all-or-nothing kind of website I believe, so you may also want to look into
http://www.indiegogo.com because with IndieGoGo you can choose to accept any funds you receive. Kickstarter refunds it all if you don't make your target. I'm using IndieGoGo right now (
http://www.indiegogo.com/citywithnoanimals) and they've got some really great tips on how to run a campaign
Post updates here on the forum and send them to the campaign as you progress!
And definitely include your bitcoin address on both the project page on your website and the indiegogo campaign, since we want to promote using bitcoin.
Make sure you link to starter websites so people can get a wallet and bitcoins, etc if they're inspired by your campaign.
Good luck!
