# audioscrobbler.pl - (c) Frank 'yogan' Blendinger (yogan@intoxicatedmind.net)
# -----------------------------------------------------------------------------
# 
# Gets your last played song from the audioscrobbler.com textfeed and prints it
# either to the current channel/query or privately to you. You need an account
# on audioscrobbler.com and an running plugin for you favorite media player.
# 
# A quick and dirty hack, done without any perl or irssi-scripting knowledge.
# Pure coincidence if it works. ;)
#
# -----------------------------------------------------------------------------
#
# USAGE:
# 	/anp [-p]
# 	  Prints your currently playing song to the active channel/query. If
# 	  the parameter -p is given, it will only be shown to yourself.
# 	
# 	Don't forget to /set audioscrobbler_nick <your-audioscrobbler-nick>
#
# TODO:
# 	- fix crashing when audioscrobbler.com not reachable (user-definable
# 	  timeout)
# 	- /anp <nick> - see what other users are playing
# 	- last5 command
#
# HISTORY:
# 	- 2004-10-08 - v0.1
# 	  Initial release
# 	  
# 	- 2004-10-13 - v0.2
# 	  Instead of two commands (/anp and /anppriv), /anp now has a -p
# 	  parameter to choose private display.
#
# 	- 2004-12-23 - v0.2.1
# 	  Small bugfix. Stupid audioscrobbler won't fill the first line
# 	  in the textfeed anymore. Now just using the second line. Please
# 	  note that this could still show some quite old song, if you haven't
# 	  submitted a new one yet. Only thing I could do about that is checking
# 	  the timestamp, but who give's a shit anyway?
