Extras are little pieces of software written by developers to enhance Skype and give you even more features. With Skype 3.0 you can now open Extras from the ‘Do More’ button and start making use of them straight away. Every week we’ll post details of one of our premium Extras to tell you all about them and the benefits you can get from using them.

We’re starting off with Last.fm, the world’s largest social music platform. Last.fm lets you listen to different music and builds an online profile based on your music tastes. It then creates a customised radio for you and recommends music and events.

By installing the Last.fm Extra, you can listen to free customisable radio. It’s also possible to let your friends know what you are listening to at that exact moment. If they like it too they can always call you to chat about the band's latest album!

It’s easy to start listening to music through Skype. Just like all the other Extras, all you have to do is go to the ‘Do More’ button in Skype and follow the instructions to install.

Then when it’s installed, you can launch Last.fm from the ‘Do More’ button. Try typing in any artist you like and Last.fm will recommend an artist that’s similar to your request to listen to and see whether you like them.

If you do, you can choose what you want to do next, from recommending the song to a friend, to making sure that you never hear the song again if you hate it.

If you want your friends to know what music you’ve discovered, select the box ‘Show what I’m listening to in my mood message’ and the name of the track and the artist will be displayed there for all your contacts to see.

If you’re a developer and would like to develop and distribute similar extras for Skype, keep an eye on our Developer Zone and the Developer blog.
