CHICAGO — Napster Inc., the online music community that rose from a dorm room project to became the scourge of the global recording industry, is being purchased by Best Buy Inc. for nearly $127 million as the electronics retailer tries to boost its digital music business.

The $2.65 per share all-cash deal announced yesterday is nearly double the music network's Friday closing price but a small sum to pay for Best Buy, which gets access to Napster's 700,000 subscribers who pay a monthly fee to access digital music catalogs.

"It's not a huge investment, but it definitely has brand recognition," said Morningstar analyst Brady Lemos, who said Best Buy also benefits from the acquisition of technical expertise about the digital music industry.

In a statement, Best Buy valued the deal at $121 million, and said the difference was due to unvested employee stock awards at Napster. According to its most recent quarterly filing, Napster had about 47.9 million shares outstanding as of Aug. 8, implying a price of $126.9 million.

Napster, a once-free file-sharing network incorporated in 2000, was a favorite tool among cheap college students earlier in the decade. But as the service gained popularity, the company became the sworn enemy of heavy metal band Metallica and along the way fueled a cultural, legal and political debate about copyrights and intellectual property while at the same time helping popularize digital music.

"We believe Best Buy will be an ideal partner for Napster and are very excited by the benefits that this transaction delivers to our shareholders, partners and employees," Napster Chairman and Chief Executive Chris Gorog said in a statement.

Richfield, Minn.-based Best Buy said it doesn't plan to relocate Napster from its Los Angeles headquarters or make any "significant" personnel changes.

Morgan Keegan & Co. analyst Tavis McCourt called the offer a "potentially intriguing acquisition."

"Best Buy has been making headway into selling mobile handsets recently, and has been offering a Best Buy Music Store (powered by Rhapsody) for some time," McCourt told investors in a research note. "We expect Best Buy will likely utilize Napster as a means of bundling digital content with its PC and mobile handset offerings."

Standard & Poor's analyst Michael Souers said Napster will play an important role in Best Buy's efforts to fuel the growth of its digital music division.

"We see (Best Buy) continuing to expand offerings in digital media content and we think (Napster) will play an important role in this transformation," he told investors.

The deal is also a boon for Napster, which last month reported a loss of $4.4 million, or 10 cents per share, as revenue slid 6 percent. Experts said it would likely face more struggles on its own as the popularity of Apple Inc.'s iTunes grows.
