I thought we had a separate idea for different rules for different groups of albums! Feel free to add it. My feeling is that rulesets should be applicable depending on a set of criteria. One of these could be location - which folder the files are in. Others could be whether the album is a compilation, a single, in a given genre etc etc.

I also mostly use bliss to clean up my music to listen through my Sonos system, so I'm quite keen on this idea. I have already customised bliss to do this fairly well I think but it's taken a bit of testing and trial and error. I think this rule-set would be a big drawcard to a lot of new Sonos users who don't necessarily want to (or feel comfortable or even know how to) fiddle with the details of bliss rules, but just want one button to achieve bliss quickly and getting tidy and beautiful music through their Sonos systems.

I can see another variant of this ruleset to set up a "high-quality" bliss ruleset which has lossless music files and high resolution imagery for use on a home system. Plus a 2nd ruleset to run on possibly a subset of the music in a different folder at higher compression (smaller music files) and lower image resolution that would be used for a mobile device (ipod, phone etc). Perhaps the 2nd ruleset already exists somewhere in bliss - if so just let me know?

I really like this idea (and its generalisation to other music players/environments).
