Mining blogs is a great way to stay cutting edge on any topic, but with information spread out over so many sites, how can you possibly keep track of the latest cat to have cheese hilariously put on its head? Helping you at least keep track of music is...Muzic.
The handiwork of four tech-savvy audiophiles, Muzic's a new tunes discovery site boasting a real-time stream of tracks being written about & posted on hundreds of music blogs (each vetted by the founders), plus direct links to listen to/download each one, a far more efficient acquisition method than going cheek to cheek with headphone-wearing strangers only to learn they're still stuck on Chris de Burgh. Troll the constantly updating homepage for cuts (or filter by genre, tags like East Coast and Avant Garde, specific titles/artists, etc), each listed with a blurb from the blog it came from and a direct link to the source; to stream and/or download, simply hit "Get Song" via a pop-up toolbar, also what any impromptu watering hole becomes when Fred Durst shows up. Recently posted pleasures include "Zebra" by Beach House (found on WA-based Fense Post), "Born Free" by M.I.A. (from the Swedish blog First Up!), and "Fort Porkchop" by Baby Birds Don't Drink Milk; the best performers make it into a tag cloud highlighting "Artists Happening Now", which doesn't include Fred Durst. What, too soon?
If you insist on doing it yourself, check out the mega-list of 900+ blogs Muz deems worthy sources, though spending all day trolling blogs is definitely Why You're Fat.
