FoxyTunes is releasing a new version that has several upgrades, and a new feature, Signatunes, letting you add music to your emails and blog posts. The new version will be launched tomorrow.
Signatunes comes with the new FoxyTunes upgrade, and shows up in your message editor in services like Yahoo Mail. The FoxyTunes icon, when clicked, will add your currently playing song to your email message or blog post. Signatunes currently works with Facebook Notes and Mail, Yahoo, GMail, MySpace blogs, AOL Mail, Horde, WordPress, Hotmail and SquirrelMail. The song appears to the recipients as a link for the song directing to FoxyTunes' website.
Additional feature upgrades include a web search or lyrics, artist images, videos, etc., a desktop widget to let you listen to music outside of your Firefox browser, and a podcast preview to find music that you'd like to subscribe to. There's also an info box for your dashboard to offer more data on songs, album art, recent history and more. There is not yet a Mac version (update: actually there is - works on Linux too). FoxyTunes' last announcement was a Twitter inclusion to its service.
