BEIJING (AP) -- Customers in China of Apple Inc.'s iTunes online music store were unable to download songs this week, and an activist group said Beijing was trying to block access to a new Tibet-themed album.

In Internet forums, iTunes users complained they had been unable to download music since Monday. That was a day after the Art of Peace Foundation announced the release of "Songs for Tibet," with music by Sting, Alanis Morissette, Garbage and others, and a 15-minute talk by the Dalai Lama, the exiled Tibetan leader.

Beijing encourages internet use for education and business use but tries to block access to foreign sites run by dissidents and human rights and Tibet activists.

The Ministry of Industry and Information Technology, which regulates Internet use, did not respond to a request for comment. A spokeswoman for the Ministry of Public Security said she had no information.
