Update File Read In Using PHP

[faint545]

Here is my situation. I have a website with an online radio stream. On the webpage, I have a small section where it tells visitors, what song is currently playing on the radio stream. Problem is, when a song is changed, the ticker doesn't until you refresh the page. My question is, is there a way to get this ticker to refresh on it's own (without refreshing the page) using PHP? Here's how I have everything set up.

Website is set up using Drupal.

Radio stream is setup using edcast, icecast2, zararadio, and fling ftp. Zararadio is used to play the songs I want played on the radio, as well as write the current song metadata to a text file and then I have fling ftp set up to FTP that text file to my website's server whenever the text file is updated. I then have a snippet of php code that read from that file and prints the contents on the web page.
