I love music. But I hate when three applications fight over which gets to play it when I click on the links at http://del.icio.us/popular/system:filetype:mp3 . So I decided to do something about it: you will now notice a 
to the left of every mp3 link. Go ahead, click on it and enjoy the peaceful beauty when the music just plays.
We recently added a way to play back mp3 links posted to del.icio.us without leaving the page or browser. Many of you loved this solution and asked if you could put it on your blog or website. I now have an answer for you – yes you can! PlayTagger is a simple javascript you include on your site that automatically makes any mp3 link playable on your page. It also includes a link that allows visitors to easily post the mp3 to del.icio.us.
The PlayTagger code and example are located here: del.icio.us/help/playtagger
P.S. Sorry this took so long. We have actually had the code done for two weeks, but choosing the name proved harder than we could have imagined. Some names that didn't make the cut: playDots, medialicious, mmmmMp3, del.icio.us mp3 player, ClickNipples, etc.
