Old Code – class::Scrobbler
A long time ago I wrote some PHP code for the AudioScrobbler API. I wrote it as more of a proof-of-concept and never touched it again, so I don’t know how well it works. I may play around with it some more as part of a test just to make sure the thing still works, but I wanted to share my code with you.
Source available at codepad and continued after the break.
