The list also includes a single entry category called, “great big stick things that you swish about” and another called “sites with lots of cowbell”.

“2008 has been a startling year for innovation in digital music. We’ve been covering startups all year in our daily bulletin, not to mention our work with the Popkomm-IMEA and MidemNet New Business Showcase awards. So we thought we’d round up some of the most interesting startups from this year,” the industry analysts said.
