Grooveshark may have been booted from both the iTunes App Store and Android Market, but that's not stopping the controversial music streaming startup from forging ahead with its mobile strategy. Rather than going back and forth with Apple and Google, the company has taken matters into its own hands by launching a Web app that forgoes Flash in favor of HTML5.

The Grooveshark HTML5 app can stream music from any modern mobile browser, including Safari on the iPad, iPhone and iPod Touch. Until now, the service wouldn't work on (non-jailbroken) iOS devices, since the desktop Web app for Grooveshark utilizes Flash for playback.

Things are not looking good for Grooveshark. The controversial music streaming site has been banned from the major mobile app stores and is in the process of being sued by Universal Music Group for copyright infringement. Yes, that's the same UMG that apparently thinks its right to remove content from the Internet goes beyond what it actually owns.

But this week, the label was joined by a few of its industry allies in its fight against Grooveshark. Sony and Warner Music Group are piling on and joining the lawsuit against the service. Since UMG's lawsuit was filed, leaked emails and blog comments from purported Grooveshark employees have shined new light on the extent of the alleged infringement.

I'll never forget when I first discovered Napster. I was in high school and had heard about it from a friend. As an avid music fan, I was delighted to suddenly find myself with access to a seemingly limitless trove of songs, some of which were previously available only on $40 CD-R bootlegs in the back of record shops where they also sold paraphernalia strictly designed for smoking tobacco and only tobacco.

I never abandoned purchasing music all together, but the MP3 struck me as a far more convenient format than the compact disc, and Napster gave me quick and easy access to a world of MP3's. When Radiohead's "Kid A" showed up on Napster weeks before the CD was available in stores, what was I supposed to do? Ignore it?

The music streaming site Grooveshark is no stranger to the ire of the music industry. The service's approach to hosting and streaming songs has resulted in a barrage of criticism from industry players, as well as a handful of lawsuits.

The latest lawsuit is actually the second one to be filed by Universal Music Group, the biggest of the major record companies. This time, UMG is suing over a claim that Grooveshark employees were required to bulk-upload music files to the service, and even got a monetary bonus for beating their upload quota. The lawsuit demands $150,000 per alleged infringement, which works out to about $17 billion, as Digital Music News points out.

The peer-to-peer music streaming service Grooveshark has had a series of run-ins with mobile providers. Its iOS app was pulled from the App Store in August of last year, and its Android app was booted from the Android Marketplace earlier this month.

The company has now fired back at the music industry and at Apple and Google, contending there's nothing illegal about its app.

There is simply nothing like Twitter for being a fly on the wall. People sit at work and tweet about what they're doing. They tweet at night, they tweet in the morning and they tweet a lot on the weekends - find a vein of good tweets from a group of people you want to learn from, watch it over time and the world is your oyster.

That's my theory, anyway. One of the things I'm interested in tracking are the streaming music services. So tonight I built a Twitter list of people who work at Rdio, Pandora, Mog and Spotify. (Then I remembered Grooveshark!) Give it a click and you can follow it too. I'll show you how I made it below - and of course this process could be applied to any field.

The music-streaming app Grooveshark has been booted out just eight days after it hit the App Store, thanks to a complaint by Universal Music Group UK.

The Grooveshark app was initially rejected by Apple and relegated to the unauthorized Cydia app directory for jailbroken devices. Grooveshark spent a year tweaking the app to make it legal and it appeared in the App Store on August 8. But today, it was gone.

Lately, it feels like you can't turn around without hearing about another streaming music app for the iPhone, and today's no exception. Grooveshark, the streaming repository of user-submitted music, has finally made it through the gauntlet known as Apple's App Store submission process and is available for the iPhone.

The release comes on the heels of several other streaming music apps' admission to the App Store and offers a cheap, though sometimes catalog-light, alternative to other services.

When Apple purchased the cloud-based music streaming service Lala in December of 2009 and then announced a few months later that it was planning to shut it down, many hoped that this signaled Apple's intentions to launch its own cloud-based version under the iTunes label. And so, a replacement for Lala was on many people's wishlist for announcements they hoped to hear Steve Jobs make today at WWDC.

But unfortunately, Jobs had no such news.

Hype Machine, the smart, long-running MP3 blog aggregator, has posted its annual collection of the most-blogged-about albums, songs and musical artists of the year. Once again, the project is a pleasure to consume and will unfold throughout the month of January. Top albums 50 through 41, Mumford and Sons through Monsters of Folk, are available now in full for streaming.

The album collection combines weighted rankings - based on submitted top 10 lists from 550 MP3 blogs - with a widget from Grooveshark to listen to the album, and a Creative Commons photo of each band. It's quite nice. The newest addition to the project is unusually low-tech; it's artist renditions of the top 50 musical artists of the year.
