I have never had this problem before. Yahoo says since it's buffering it's not their problem, but an internet problem. I say bull roar. I have no problem playing any mp3's on any of our phones, tablets or desktop except for my demo page.
Now I did get them to work on one cell phone. My wifes phone works occasionally and and it does not work on the desktop.
Could you please see if they work on your device and tell me what kind of device you are using and what kind of service, broadband, dsl, cable, dial? And if you do have a problem do you have a similar problem playing other mp3's off the internet?
Thanks
