-- Warner Music Group’s stock price has given up a good portion of its gains this year. Since reaching a high of $8.01 on April 14, shares of Warner have dropped 30.2% to $6.15 at Wednesday’s close. The stock was down 6.68% on Tuesday and 4.35% on Wednesday. But it’s still up 22.4% from its 2010 low of $4.77 on January 25.

-- Sony Corp. and Google have partnered to offer new cloud-based products. The two companies are exploring the joint development of new Android-based hardware products for the home, mobile and personal product categories, according to a release.

-- The National debuted with a strong first week of 50,000 sales of the band’s latest album, "High Violet" (4AD). Perhaps the band’s Vevo live concert broadcast played a part in that? Hard to say. A Vevo spokesperson would not share statistics on the size of that broadcast’s audience. TubeMogul, however, was able to share with Billboard a figure that helps put the broadcast into some perspective. According to the company, in the 48 hours after the broadcast videos taken from the National’s Friday night broadcast and posted to the band’s official channel had been streamed 9.3% as many times as videos taken from U2’s 2009 live YouTube broadcast over the same period of time. Looked at a different way, 12 times as many people watched U2’s post-broadcast videos as watched the National’s post-broadcast videos. Given the stature of both U2 and that particular event, those figures don’t seem too bad. To be clear, TubeMogul was not able to track the number of real-time streams of the National’s Friday night broadcast. It tracked the number of streams amassed by the songs made available for replay after the broadcast was over. In other words, TubeMogul tracked reruns of individual song plays, not the live broadcast.

-- Hot Topic’s first quarter of fiscal 2010 results include a loss of $900,000, or $0.02 per diluted share, related to ShockHound, the company’s music merchandise and download e-commerce store. That represents half the company’s $1.8 million net loss reported in the quarter. Shockhound lost $3.1 million in fiscal 2009 and $2.3 million in fiscal 2008 despite launching in the third quarter of that year. (SEC filing)

-- SoundExchange was sitting on about $200 million of undisbursed royalties at the end of 2008, an amount confirmed to Digital Music News by a SoundExchange executive. Actually, the unpaid royalties balance was about $260 million at the end of 2008. SoundExchange’s Laura Williams confirmed the actual figure related to unpaid royalties was closer to $200 million (due to payments for accrued royalties). However, the $200 million figure is not new. The confirmation from SoundExchange is the key addition to this story. Amounts mentioned by DMN have actually been mentioned before. One was a February 4, 2010 post at P2PNet that cited a balance of $256 million in SoundExchange’s unpaid royalties account. The other was in a December 29, 2009 post at P2Pnet that quoted a letter sent by attorney Fred Wilhelms in which he wrote that the pool was “well over $200 million as I write this.” Neither post included a confirmation from a SoundExchange representative. In any case, the numbers that have been reported are far from the $50 million figure reported in a March 2010 article by the Los Angeles Times – unless the growth of that account has somehow reversed direction in the 15 months following the end-of-2008 audit.

-- Brendan Mulligan, CEO of ArtistData, says to musicians, “Sign up for for Square right now.” Not Foursquare, the hot geolocation app. Square, the iPhone app that for musicians would allow fans to pay for merchandise at live shows with their credit cards. Each account comes with a free card reader that is plugged into the device. “And the rates are incredibly fair with no contract or monthly fee,” adds Mulligan. “That means if you don’t like it, you can just stop using it. There’s no reason not to try it.” Currently the Square app works only on iPhones, iPod Touches and iPads and is available only in the U.S. (Music Think Tank)
