Well I'd looked it up and apparently international royalty payments for performing rights are collected by the collection society of the composer's home country. So if you reside in the UK and someone listens to your music in Sweden, ultimately you will get your cheque from PRS UK. As far as I know Stefani Germanotta (known as Lady GaGa) resides in the United States which means she must be a member of ASCAP, so I don't really understand how could she get a cheque from STIM at all.
