Note 1: Last.FM request that you do not query their servers more than once per second. Imagine 50,000 websites all performing 10 queries at the same time. To be sure that mine never will, I fetch the XML files once every 5 minutes, and then query them locally. The code I used to do that can be found
here.
Note 2: 'allow_url_fopen' needs to be set to "on" in your php.ini file. This is something your hosting company might be reluctant to turn on, and for good reason. It is not exactly secure, but it does make life so much easier.
