Internet Radio Macbook ???

Hi

I've tried accessing internet radio via itunes. The station plays but "every 3 seconds" a progress bar pops up and confirms "rebuffering stream" This continuously interferes with the music being played. What must i do to prevent this ?

Pick a different station.

Verify you are receiving the bandwidth you're paying for - easy test at speedtest.net.
Upgrade to a higher speed service from your ISP.
