Adding mp3 Files To A Site

Hello
What is the most effective way to add mp3 audio to a page so it can be played back using quicktime or windows media player, or automatically be played (listened to) in the viewers media player of choice?
I can embed both players next to each other, but should the viewer only have one of the 2 players installed, a blank area appears offsetting the layouts appearance.
I don't necessarily need the player to be visible on the page, but want play back to be controlled by the page viewer.
Is there a way to have a "Listen Here" link, that when clicked will allow the viewers default player (should they not use QT or WMP) to take over and play the audio in another browser window they can minimize and continue viewing while listening?
Many people like the light show when playing music on windows media player, and when embedded in the page, this seems to be no longer an option.
Do mp3 files need to be compressed like images for faster page loads?
Clueless.

Hey Barry
The most effective way is to give the user the ability to have the choice of downloading the mp3 file and listening with a local intsalled mp3 player. Second is the option to give an embeeded player a tray. But with this you're limited and can't bring any other action into your site while the user is listening (beside you're using AJAX or FRAMES for your site). I would go with the first option while giving the users some indtroduction what they can excpect from the file.

For example:
Dear User,
thanks for taking the time and visiting our new site. We are currently in production phase and can you give a small excerpt of our coming portfolio. To be able to get this working you need a local MP3 player installed, such as winamp, media player, itunes or any other. Select the file you prefer below. Thank you and enjoy.
Available Files:
[icon winamp] Download Winamp MP3 File
[icon mediaplayer] Download MediaPlayer MP3 File
[icon itunes] Download iTunes MPe File
*****************************************
This way you give the user the full control of taking action. They can listen to it whilst browsing your or other sites. They can download the files and forget about them. They can save them, copy to an ipod and listen elsewhere, etc. etc.
You could also convert the files into their specific player extensions like *.wmv just for media player, etc. This isn't really needed cause all of the above players support MP3 audio files.
Hope this helps. Take care
Manuel
