Not quite what he&#x27;s looking for. You can add more variety to make a station of music that includes x OR y OR z, but you can&#x27;t make a station that plays songs with x AND y AND z.<p>I&#x27;ve run into this as well. You try to make a station that plays piano rock, and Pandora goes &quot;Hey, here&#x27;s a song that fits! It has: 1)  mixed acoustic and electric instrumentation, 2)  major key tonality, and 3) mellow rock instrumentation.&quot; It won&#x27;t care that every song you&#x27;ve added to the station was tagged with acoustic rhythm piano, all tags are equal to the matching algorithm.
