Include more query options when creating intelligent playlists

Hello,

Similar to the AND/OR post i have made today, another nice to have feature would be the possibility to have options similar to regex (regular expressions) when creating the playlists. This would actually make them more "intelligent" if you prefer.

Example: Create a playlist that match any tracks, allowing us to have the following options available:

1) Use of case sensitive words;

2) Contains multiple words in the SAME condition (separated by commas or semicolons);

3) Does not contain multiple words in the SAME condition (separated by commas or semicolons);

4) Include AND/OR/NOT options (in a drop down box or similar) in the SAME condition.

Take a look at this excellent example coming from Magic The Gathering public database (not trying to do any kind of publicity here, just for the sake of simplicity by seeing an actual real-life example):

Thank you in advance,
