Play all lastfm:// links at once

A nice way to play all the "lastfm://" links in the last.fm player at once.
(applications used: textpad, ruby [windows])

• copy html sourcecode to textpad, replace all "\n" -> ""
  
• copy modified sourcecode to clipboard
• start cmd.exe, type: irb [ENTER]
  
  
  
• type following into the ruby shell for putting the sourcecode into a variable
  input = <<EOT
/* paste the html code here
important: use the shortkey
[Shift]+[Insert]
or it will take hours
to insert the text */
EOT
• now find all "lastfm://" uris:
  uris = input.scan(
%r|lastfm://play/tracks/[0-9,]+|).join("")
• join the found uris into one uri:
  uri = 'lastfm://play/tracks/' +
uris.gsub(%r|lastfm://play/tracks/|, ',')
• copy the result from the shell into textpad
• textpad: replace all "\n" -> ""

Now the result string can be entered in the address line of a web browser and when the "lastfm:" protocol-identifier is associated to the last.fm player all the tracks will be played there.

The next step would be to implement all the steps in javascript and put it into a greasemonkey script to automatize them.

PS: This Method is useful, when you want to create a playlist for recording the added tracks by e.g. TheLastRipper and hear a preview of the tracks before adding them to the playlist. Also it is useful when you want to play a playlist containing full-length available tracks on last.fm.
