"David Callé has released a Grooveshark scrope for the Unity Music lens which lets you search for music on Grooveshark from Dash. The new scope uses the free Grooveshark API and clicking on a search result opens a new tab in your default browser, playing the selected song.
According to David, there are a few known issues though, such as:
- the results open in different tabs and aren't enqueued
- results in the local collection are not deduplicated
- some searches don't display any results due to some encoding errors
- sometimes cover art isn't displayed the first time you search for something"
Thanks to Andrew and David
