Last.fm "Add to mySpace" - how?!

[Zaid_W1red]

Hey Guys,

I've ben racking my head trying work work out how the bright spark at last.fm achieved the 'add to my myspace' function to their widgets!

Does anyone have any ideas?

I found the following PHP class: http://www.weberdev.com/get_example-4510.html - but the scripts old which is why I assume it doesn't work, and my attempts to contact the dev have been unsuccessful!

Appreciate anyones input :D

Thanks for the reply!

Im not that familiar with their community - but I'll certainly try it now!

After trawling the web I pieced this together - it works, but its slow and pretty hit and miss.

Would any be interested In collaborating on this?
