Constant Media Player

[kingaman]

I am developing a site for a client who wants a media player with a few of his songs. - He wants the player to begin when the user first visits the site, and then continue playing as the user navigates through the page (of course with the option to turn it of if they so wish).

I am having trouble working out how to do this - as the player needs to continue smoothly between pages as it would be very disjointed and annoying if it were to restart every time a page was loaded.

I can only think of this being done with either frames or a pop-up window - neither of which are preferable - however i'm going with the pop-up option.
Does anyone have any other ideas of how this can be done?
I need to speak to my client about it in just under 12 hours.

An iframe would be less intrusive than the popup option, the only problem is the SEO problems associated with the iframe.

Designing the whole site in flash would be another option, but i'm not really a big fan of flash websites.. I personally think that flash has the same SEO problems as the iframe.

Have you suggested that the user can click a link to launch the player, rather than the player popping up when they load the site, as most people have pop-up blockers by default now.
