KeySharky

KeySharky is an add-on for Mozilla Firefox that lets you use different keyboard shortcuts when you're listening to music from the popular Grooveshark website.

Once you have it installed, you just need to press a series of simple keyboard shortcuts (which are not configurable) that you can use to pause and play songs, select the next or previous song, and even give each one a positive or negative vote.

KeySharky is an essential add-on for anyone who uses Grooveshark regularly. With its minimum consumption of resources, it makes navigating the website much easier.
