Starting from yesterday it possible to listen to full length tracks on last.fm on demand. Before it was just possible to listen to 30sec previews on demand or to full length shuffled tracks ("radio style").

So read the full announcement here.

 My opinon: another interesting step towards new ways of buying or getting music!

The way I am listening to music is changing nowadays. It is getting better actually, and as music is important for me I appreciate this development. So, in fact listening to music and most importantly finding new good music is not easy and does not happen by it's own. But at least - its getting easier now.
