<p>For example, if I set "Year of Publication" to -0.5, and my seed song has a Year of "1973", does that mean that another song with year 1973 is less likely to be selected than another song with a year of 1974 (or 2014 or 1944), assuming everything else is equal?</p>
</blockquote>
<p>Exactly.</p>
<p>If you set a negative weight for the year rule, it essentially means that tracks that were released in a similar time frame as your seed song are indeed ranked lower than other identical songs that have a completely different release year.</p>
<blockquote>
<p>If I set a parameter (say, "Instrumentation") to be 0.0, does that mean that Instrumentation will have no effect at all in the returned result?</p>
</blockquote>
<p>Exactly. It won't affect the result.</p>
<blockquote>
<p>Also, Hendrik, could you explain what the process references when assessing things like "Popularity" and "Similar Artist"?</p>
</blockquote>
<p>Popularity is a measure of how many people have a certain track.<br>
Similar artist depends to a large degree on LastFM data, but also uses WikiData data.</p></div>hendrik
