There used to be libre.fm and it looks like there still is. The API was designed to be a drop-in replacement for last.fm. Last time I checked it was missing some stuff. They also have a lasttolibre tool for migrating your data. If last.fm goes away, this is where you go and what you use to do it. Or don't wait and move now, if you want.
