Price recently posted an entry on TuneCore's blog titled "Grooveshark: Trolling The Sea Of Artists To Make A Buck?".
In it, he alludes to Grooveshark's "stealing from artists" via legal loopholes that have led to the site amassing 30 million users, and its resulting appeal to potential advertisers "Just think of all the money Grooveshark makes by selling ads," he wrote.
"There is just one really big, big problem," he added "They don't get licenses and don't pay the artists, the labels and/or the songwriters for the use of the music that's making them tons of money. I can assure you, 99% of the hundreds of thousands of TuneCore Artists whose music is in Grooveshark have not been paid a single penny.
"Said more simply: ARTISTS SHOULD BE PAID FOR THE USE OF THEIR MUSIC!"
He goes on to point out the "legally questionable practice" Grooveshark employs through which users put music into its system and thus shields the service from being sued as long as it complies with take-down orders.
Writing about his personal dealing with Grooveshark, Price said: "I've never experienced anyone trying to so hard to convince me that 2+2 does not equal 4. They wanted TuneCore to enter into a deal with them, but the whole thing made me sick."
"My opinion: Grooveshark is a fish rotting from the head down. The people running it are immoral and could care less about who and/or what they hurt as long as they make money."
Price concludes the blog post with a call-to-action for artists: "So what can you do if your recordings or songs are on Grooveshark without your authorization? Number one, tell your fans NOT TO USE THEM. Start a Twitter "Boycott Grooveshark" campaign. Even better, learn who is advertising with Grooveshark and then tweet, email and/or call those companies and tell them to stop giving Grooveshark money."

This is the latest attack on Grooveshark following EMI terminating its licensing agreement with the service, a lawsuit by the major record labels, the termination of the service in Germany and a Danish court order for ISPs to block it.
