Bren, formerly of Slacker Manager fame, showed me this great little tip today. Playtagger is a feature brought to us by del.icio.us.

Play Tagger is a neat little tool that allows you to easily play mp3 files directly on del.icio.us (see the popular mp3 bookmarks), and you can have it for your website or blog too. Include this tiny javascript in your HTML, and your mp3 links will automatically become playable right on the page. In addition, your visitors will have the opportunity to easily tag and post the mp3 link to del.icio.us. This script is very lightweight, as is the flash movie that plays on demand.

Probably the most useful part is you can drag a link to your bookmark bar. If you are browsing a page with a link to a MP3 file, give that bookmark a click, and you will be able to play that MP3 inline on the page, rather than being required to download it. Very slick.
