I have a page for a music track of the week, i have embedded the audio on the page, this works okay, but can i keep the audio playing while the viewer changes the web page to another page?. I would also like to have multiple tracks on the page and the viewer choose a track, is this possible? if so any hints would be gratefully recieved.

Since its embedded in the page, if you change to page, the embedded player is lost.
Some things that can work,

• launch the page with the player in a new window
• launch the media player as a separate process
• <shiver>use frames</shiver> so the frame with the embedded player is not lost

FYI, make sure the music is user initiated. Most (99.99%, maybe more) users hate music that just starts playing on page load.

my suggestion would be to use a simple implementation of an <iframe>. ifames have their problems and are looked down upon by a lot of web developers but for a basic implementation like this, they'll work pefrectly.

Assuming a traditional layout, your main page would include your banner, nav bar and any other object which would be constant throuout all the pages.

then, through targeted links, you can have a content <iframe> which will bring up any content via the nav bar links.

then, a small iframe as a footer, with the audio player.
the most user friendly implementation of an aduio player w/ playlist might be to use a flash mp3 player (a very good one is avaible here: http://www.jeroenwijering.com/?item=Flash_MP3_Player)
