OS X: Shiny Groove is a minimal but feature-packed Grooveshark player that lets you listen to your entire library, browse your playlists, or search and discover new music all from a mini-player that supports keyboard shortcuts, multimedia keys, even remotes like headphone controls or the Apple remote.
Grooveshark is one of our favorite streaming music services, and it looks great on the web but its desktop app could be better. Shiny Groove makes up for it with a great player that—even though it's in beta—is remarkably polished.
Shiny Groove is tiny, can be controlled with media keys or remote controls, supports key commands, and packs all of the features of Grooveshark on the web into a tiny box that sits in the corner of your screen. You can expand the player to get full access to your playlists, search, and other features, and then minimize it to the miniplayer when you're ready to listen. The app downloads and displays artwork for you, and flips artwork over as the songs change. grab the player and shake your mouse to hide it from the desktop, or use the menubar icon to toggle visibility. Shiny Groove is free while it's in beta. Give it a try at the link below.
