I highly doubt anyone has ridden yet. They just finished re-installing the lift a few days ago.
It sounds like he just got a behind the scenes tour of the attraction. Sea World held several tours before they opened Manta, so it's not surprising Universal is doing the same, albeit in a much smaller/less public manner.
There's another article here:

He also apparently got a hard hat tour of the site, and is also a British journalist... why the overseas favoritism, Uni? Anyway, he confirms one of the songs to be "Gloria Gaynor - I Will Survive". So it looks like we know two of the songs now, unless these guys are just making these articles up as they go.
In actual attraction news, Johnnyupsidedown has added some new construction pictures to his website from this morning:

And finally, I found this article rather amusing:

I assume english isn't the primary language of the guy who wrote that article, as he assumed "World's Highest Tech Roller Coaster" meant "World's Highest Tech Roller Coaster" and that when they stated the ride was 3,800 feet long, he assumed that to mean it was 3,800 feet high.
