There is a famous taglline, “No Music, No Life”. I guess music is really important and it is a part of our life. Soundzit is a new service that is developed using the Youtube API. With Soundzit, you can click and listen over 300 million music online instantly.
Besides that, users have the option to purchase music on iTunes and listen to high quality through a link on all music. Plus, users can choose to embed the customizable Soundzit music player on your site or blog. Basically, Soundzit is a very simple to use site, and maybe in the future many more new features will be available to better enhance the service.
Seems like a reseller of iTunes, not sure that iTunes have so much music tracks there.
