I've listened to some music that would cut in and out constantly, making it impossible to follow if you're trying to listen to it. I've had some that would randomly be interupted by a human speaking, "Thank you for calling ___, we apologize for the wait," so you'd think it was finally someone picking up and dash for the speaker phone, only to have it continue with the music.
For my very own company, the music for employee/tech support is so bad that we can't actually listen to it on company phones, it is impossible to hear so unless you're willing to wait for 3 hours (actual time of tech support wait, trust me) with the phone to your ear while checking out customers, you're SOL.
This isn't just my phone, either. I've used company phones, home phones, and someone's fancy Verizon phone, the kind that's designed to play mp3s so the speaker quality is top of the line.
Anyone else feel the same way?
