With the huge popularity of online social networks in recent years, combined with the unstoppable demand for everything music via the Internet, there are so many choices today that it is impossible for anyone to get a good grip on what are the best music websites, social networks, audio tools and downloads, widgets, musician hubs and more.

The Mashable Team has assembled perhaps the best all-in-one, 'essential' website directory for music and audio links ever published on the Internet. (Yeah, I know what you're saying: 'it better be good!')

Not only has the team provided screenshots, links and reviews of pre-approved quality music sites, but they also packaged it for ease of use and with no frills or hoops to jump through.

Categories include Internet radio, music discovery, social networks, music sharing applications and widgets, mobile music services, music marketplaces and charts, lyric and chart databases, music search engines and audio conversion tools.

A must have link! Hope you love it as much as I do. Thanks Mashable Team!
