Robin Good: Mixtaping.fm is a new free web service which allows anyone to put together their virtual 60-mins virtual music compilations.
Just like in the old music cassette times, compilations are made of two 30-mins sides, and differently than back then, you can throw in just about any song, track or artist that comes to mind, thanks to the integrated music search engine that Mixtaping.fm provides.
Covers can be personalized, and the service let's you see in real-time how much space your using up with each song you add. Final mixtapes can be easily shared on social media or embedded on your site/blog.
Free to use.
