This script only works with Amarok 2.0. 2.1 cannot be supported util several Amarok-bugs are fixed.
MusicExplorer is the new way to generate intelligent dynamic Playlists.
Imagine all songs you have as points in space, where similar songs lie near to each other. This script can walk around in this space and generate smooth playlists (no big jumps in genre for example).
The script can also act as a DJ. Just add the songs you definitly want to hear to the playlist and the script will automaticly reorder them and add some more songs in between such that you get nice transitions between your songs.
The first time you start, the plugin will download the coordinates for all your songs from MusicExplorer.org (poor page atm), which might take some time. You definitly want to read the FAQ that comes with this script.
Keep in mind that this is an alpha release: There are still a some API functions needed in order to finish this. If you are a developer, take a look at the TODO list. :)
MusicExplorer coordinates are powered by last.fm.
