well u can't do anything about playing when loading another page even if u have a radio or a mp3 player .... i've tested and it works like a charm another way ....but is more advanced ...if ur familiar there's no problem at all ...here's the way
........ first choose the CSS design general unpopular
now create a website in macromedia flash or flash cs4 or csm or css wizard or if u know how to add and modify a free flash template u can insert it there and after doing that u can aplly as many radios or mp3 players 'cause they wont interupt during changing pages
why ? cause u aply that webiste in flash or template in flash and that is on the main homepage so others pages are already implemented in it so if u change to any page u change inside ur flash .... get it?
..... so the mp3 player it's like he's the only one on the website that's why it doesn't see the problem .... hope u got ur answer
...or add a background music ...search for it in the forum ... but it's not working all the time ....
