the good news is that according to this page though, all modern browsers (except opera mini but who uses that) ought to support mp3 by now.  so no need for fallback formats if i interpret this correctly.

Just a heads-up that as per this article which says that Chrome is rolling out default blocking behaviour for flash, visitors may start finding that their play buttons won't work anymore.

it seems to be happening to me now (although right clicking the pixel containing the Flash plugin and clicking "run this plugin" will let you resume playing the tune).

Anyway, just reporting that this behaviour is gonna become more commonplace, which would necessitate an HTML5-only solution for song playback sooner than later.
