I am a devoted Google Chrome user and have been adding a few of the various free apps available to download if you have a Google account.
One of the apps that I have downloaded is Earbits Radio. Earbits Radio allows you to choose a style of music and it will play heaps of songs of that style. You can also log in with your Facebook account and like a song or share it with your Facebook friends.
You can access Earbits radio here: http://www.earbits.com/play/
Or get it from the Chrome Web Store here: https://chrome.google.com/webstore/detail/mgkjffcdjblaipglnmhanakilfbniihj
