I don't know much about it (as details even on the website are scarce), but Magicstereosound is certainly worth a listen.
Describing itself as 'web mod radio', it has a schedule (which you can read over the page) that covers beat, hammond and soul/R&B on a daily basis out of Milan, streaming via most online players (iTunes, Real etc).
Check out that schedule and tune in anytime via the website.
