The Digital Inspiration weblog points out a new (to me, at least) feature in Gmail that lets you play MP3s sent as attachments in an embedded flash player.
The player should look familiar, as it's pretty much the same player you're used to seeing at Google Video. The Digital Inspiration blog shows how to construct a URL that will play any MP3 file with Google's player, which is nice, but it seems like a lot of work. So I've modified the auto inline MP3 player greasemonkey script to embed the Google Player in case you prefer the look and feel of Google's player to the Musicplayer. Requires the Greasemonkey extension.
