Dragging or pasting links into a Spotify playlist works for multiple songs but not for multiple albums

Spotify offers cut/copy/paste functionality for songs. This also works for albums. With songs, you can paste multiple songs though, and this is not possible with albums. Fixing this problem, or adding the feature, will allow for all sorts of neat tools. One could, for example, write a script to generate album links for all an user's favourite albums on last.fm, or all albums present in $exotic_music_client.

To reproduce: Copy multiple songs in spotify. The clipboard will contain, for example:

http://open.spotify.com/track/7f9pfJC...
http://open.spotify.com/track/5AtDUE1...
http://open.spotify.com/track/49WfHnK...

These songs can be pasted into any playlist, or a user can drag them from, say, notepad, to a playlist, in textual form. This allows for nifty tools to be made, for example on playlist sharing sites you can post links to the songs in the playlist.

The same procedure also works with a single album link:

http://open.spotify.com/album/0hiJeb1...


But not with multiple:

http://open.spotify.com/album/0hiJeb1...
http://open.spotify.com/album/0BpCcCe...


I was hoping to write a last.fm import script based on this functionality and would find it awesome if you'd fix/improve this!
