First of, let me say this is a request for feature enhancements and as such, it has proven difficult to answer the required fields adequately.

Overview: User is unable to fully exercise standard logic statements when creating an automatic playlist

Steps to Reproduce: 
1. Have at least 4 songs in your playlist with the following info: 
NOTE:Song# and Genre# are used as variables in this example.
  <Title/Genre/Rating>
   Song1/Genre1/****
   Song2/Genre2/*****
   Song3/Genre1/*
   Song4/Genre3/*****

2. Create an automatic playlist using "Genre equals Genre1/Genre equals Genre2/Rating at least ****" 

(Do one of the following)
3a. Check the box "Add if any criteria are matched"

3b. Leave the box "Add if any criteria are matched" unchecked.

Actual Results: If 3a was preformed, user gets a playlist with all songs. (e.g. <genre> == Genre1 || <genre> == Genre2 || <rating> >= 4) If 3b was preformed, user gets an empty playlist. (e.g. <genre> == Genre1 && <genre> == Genre2 && <rating> >= 4)

Expected Results: A playlist with Song1 and Song2 but not Song3 or Song4 [e.g. ( <genre> == Genre1 || <genre> == Genre2 ) && <rating> >= 4 ]

Build Date & Platform: Binary package within Ubuntu 9.10 repository, version 0.15.5.0ubuntu5.2
