( CNN ) -- One million people registered for Apple 's music-centric social network in the first 48 hours it became available in September . But some evidence indicates that Ping may be having trouble keeping their attention . However , a collaboration between Twitter and Apple could open a backdoor to a part of the corporate workforce that has been locked out of Ping during the crucial daytime hours . With Ping -- the social service that lives within Apple 's iTunes program -- users can now post links to songs and albums to their Twitter accounts . When you find such a message in the Twitter.com stream , you can click the tweet to see a box showing details about that song from iTunes , along with a button for listening to a short snippet of the track . Twitter announced the changes on Thursday . The Ping features -- available to users in the 23 countries where the iTunes Store sells music -- is an extension of Twitter 's site overhaul last month that added a similar preview function for photos and video , a Twitter spokeswoman said . A stroll around dozens of profiles in iTunes just after the announcement reveals a less-than-vibrant place . Many Ping pages had little recent activity , aside from profile notes about new music purchases , which can be set to post automatically . The initial surge in bands creating accounts and maintaining active profiles has slowed , reports say . ( Apple declined to comment for this story . ) In order to use Ping , you must first create an iTunes account , which requires a credit card . Apple says it has some 150 million credit cards on file , but that requirement still creates an obstacle for children who do n't have credit cards of their own . Kids , aged 13 to 17 , made up Facebook 's fastest-growing demographic this summer , according to data from Inside Facebook , which tracks activity on the social network . Next , and here 's what could be a major hindrance for office workers , you must have the iTunes software installed on your computer in order to use Ping . The program does n't typically come packaged with corporate-issued machines . Companies frequently block workers from installing applications without prior approval . They do so because nearly two-thirds of all security vulnerabilities in software from Microsoft can be prevented by disallowing workers from installing programs , according to a report from security research firm BeyondTrust . But in many offices , Twitter and Facebook are just a few keystrokes away in a Web browser . The workday has proved to be prime time for Facebook , the world 's most trafficked social network . About a quarter of workers in the U.S. and U.K. say they spend more than an hour on social networking sites during office hours , according to a recent survey . Seven percent of Web pages workers accessed recently were to Facebook , observed internet security firm Network Box . Ping widens its potential daytime audience thanks to the partnership with Twitter , which has 175 million registered users . But the integration is only a one-way street , a Twitter spokeswoman said . Tweets can not be fed into Ping .
Users of Apple 's Ping social network can now send messages from within the app to Twitter . Messages from Ping can create a small widget on Twitter containing song previews . This feature could open up Ping to corporate workers who do n't have access to Ping .
