Two and a half years ago, Universal Music (UMG) sued Grooveshark (or, really, its parent company Escape Media). The case has had a few twists and turns since then, but the judge has issued a ruling that is pretty clear in suggesting that Universal Music's key argument - the the DMCA does not apply to pre-1972 songs - was a massive overreach, and the court will not accept it. Separately, the court flat-out rejected UMG's attempts to have Grooveshark's counterclaims of tortious interference dismissed. There's no way to look at this other than a pretty big win for Grooveshark and a big loss for Universal, though the case is far from over.

On the key point, Grooveshark has long argued that what it does is really no different than what YouTube does, in that it allows individuals to upload content, and if it receives a takedown notice, it proactively follows the DMCA's takedown process and removes that content. Realizing that getting around the DMCA's safe harbors was a longshot, Universal Music instead reverted to a somewhat twisted argument, saying that pre-1972 sound recordings are not covered by the DMCA, and thus there are no safe harbor protections.

To understand why they'd make this argument, you can read up on the history of pre-1972 copyrights for sound recordings - a huge mess that the US Copyright Office is still trying to figure out how to fix. But, the short version is that, currently, sound recordings from before 1972 are not technically under US federal copyright law, but various (and often crazy) state laws. Since the DMCA refers to works under federal copyright law, Universal Music's arguments is that the DMCA doesn't apply, thus the safe harbors don't apply, and Grooveshark can't rely on its safe harbor compliance to avoid liability.

If this argument sounds somewhat familiar, that's because it's the same one EMI tried to use against MP3Tunes, which failed spectacularly. The NY state court in this case appears to be well aware of that, citing the MP3Tunes case at length.

Separately, UMG failed in trying to get various counterclaims dismissed. The focus here was on claims that UMG contacted two companies - HP and INgrooves - to get them to back out of deals with Grooveshark. There are a bunch of different arguments (most pretty technical) that UMG makes to assert that these counterclaims should be dismissed, but the court isn't buying most of them. For each precedent UMG brings up, the court highlights that the facts are different here and UMG's reliance on particular caselaw "is misplaced."
