Here are a few examples:
- I am a big fan of the ECM label. In JRiver I have a playlist for all ECM titles in my collection. I also would like to organize my ECM titles by genre (Jazz, Classical, World, etc.), or by year
- Certain labels, like Blue Note, Verve, have series, like RVG Remasters, Verve Elite, etc. I would like to create playlists for these series within a label
