The IPO dance party is definitely in full swing. This season’s focus suddenly shifted to public offerings with companies like Fusion-io, Groupon and LinkedIn joining the crowd. Personalized internet radio service Pandora just went public, and hit the market strong with a recorded 46% increase in shares in the opening, pulled back a bit but still ended the day in a good run with a gain of $1.42 a share. It was a pretty solid performance by Pandora and one of the very few good news bullets in IT stock, as Yahoo, RIM, Google, Apple and Oracle plunged.

Experts believed that this relatively sturdy debut of Pandora in IPO was made possible by the scarcity of internet companies entering the stock market compared to the past decade with the insane dot.com boom. This is also the same reason behind LinkedIn’s blockbuster opening in May. There may be worries about the premature hype on Pandora and the valuation of $3 billion could possibly be overlooking competition concerns, but the current music cloud has been gained massive interests and demand.

The great deal of activity going on the music cloud space is a testimony that companies are now feeling the clamor from consumers. You’ll probably see iCloud plugs everywhere—with Apple hoping they could further improve what they offer in iTunes through this new personal cloud initiative. Nearing its US market stint with major record label deals, Swedish-born Spotify looks to challenge Apple and its music services. Along with its launch of TouchPad in July, Hewlett-Packard is also introducing a new cloud-based service through its upcoming digital locker for music and video. Another serious competitor, Sony, is now about to cross the threshold for markets in US, Australia and Europe with its existing streaming service, Music Unlimited powered by Qriocity, even launching an Android app this week.

The personal cloud reigns supreme in giant tech names like Apple and Microsoft. These vast and unexplored opportunities and hefty investments within social media and personal cloud trends are what driving IT enterprises to walk the IPO path.
