SAN FRANCISCO, May 10 (Xinhua) -- Google on Tuesday launched its long-awaited cloud-based music service Music Beta without any label licenses it originally wanted.The search giant introduced the digital music locker service at its annual I/O developer conference in San Francisco. So far, only U.S. users can access the service by requesting an invitation from Google while priorities will be given to those with the Verizon version of the Motorola Xoom tablet and attendees of the I/O conference.Since Google failed to come to a license agreement with major music labels, Music Beta is essentially a massive cloud hard drive. Users cannot share their Music Beta by Google tunes or purchase new songs. It allows users to upload 20,000 songs into the cloud, compared with Amazon Cloud Drive's 2,000 songs and 5 GB limit for free accounts.Any web-connected devices with a browser or supporting Flash can stream music from the digital locker, but the service is only for Android-powered devices.Music Beta also gets Instant Mix, a similar intelligent feature to Apple's Genius playlist creator, which creates new playlists based on a single song by analyzing its characteristics.Before unveiling the service, Google told U.S. media Monday night that the current Music Beta is not the service Google had wanted to offer and it will continue to seek licenses with major music labels.

LOS ANGELES, May 9 (Xinhua) -- Drinking alcohol may raise the likelihood among teenagers to spend more time on computers, a new study suggests.The study, conducted by researchers at Weill Cornell Medical College, was based on a survey of 264 teenagers, aged 13 to 17.Results showed that compared with teens who did not report drinking, those who drank alcohol in the last month used a computer more hours per week for non-school-related activities, including the use of social networking sites.Drinking was also linked to more frequent social networking and listening to and downloading music, according to the study published Monday in the on-line edition of the journal Addictive Behaviors.However, there was no demonstrated link between alcohol use and computer use for school work, neither there was strong link between video games and drinking or on-line shopping and drinking."While the specific factors linking teenage drinking and computer use are not yet established, it seems likely that adolescents are experimenting with drinking and activities on the Internet," said Dr. Epstein, assistant professor of public health at the college."In turn, exposure to on-line material such as alcohol advertising or alcohol-using peers on social networking sites could reinforce teens' drinking."Children are being exposed to computers and the Internet at younger ages. For this reason it's important that parents are actively involved in monitoring their children's computer usage, as well as alcohol use."Teenagers typically first experiment with alcohol at age 12 or 13, according to the study.Family risk factors include lax parental supervision and poor communication, family conflicts, inconsistent or harsh discipline and a family history of alcohol or drug abuse."According to a national study conducted by the Pew Internet and American Life Project, more than half of parents of teenagers had filters installed on the computers their child uses to block content parents find objectionable, yet many parents do not use any form of parental monitoring, particularly for older teens," Epstein said.
