Whether it’s music, marketing messages, or a combination of both, the recording should be long enough so it doesn’t loop back to where they started when they were first put on hold. If you don’t typically have long wait times, this should be no problem. If calls get stacked up sometimes, you’ll want to make sure that the recording is at least as long as your typical wait time on a busy day.
The song was immediately polarizing, as far as these things go, which the company's executives,saw as a good thing; it generated buzz on Twitter, and gave people something to talk about when they got on the phone. Some people hated it, Cornell said, and others loved it so much they downloaded it. Cornell was invited to do a live performance for one company, where sales staff listened to the song all day long. It wasn't meant to fade into the background, and perhaps that's why it's lasted so long.

You have a captive audience on hold. On-Hold messages—while they wait even for a few moments— are very important for any business. Especially if you have a customer service line or you conduct any kind of business over the phone, then you need a message on-hold production provided by our division OnHoldAudio.net.
No one wants to be stuck on hold with silence (30 seconds feels like 5 minutes!).
