(I admit I have a bias towards the blues/heavy metal guitar end of the spectrum myself)

There is a little-known feature available in config.sys (that the good guys @ empeg put in pretty much just for me!) that you might find interesting.

If you put these lines into your config.ini file:

[shuffle]
deduplicate=0

you get the following behavior: Normally, when you append or insert several playlists together and then shuffle them, any duplicate tracks (tracks that appeared in two or more of the combined playlists) are automatically deleted. If you have the two lines shown above in your config.ini, they will not be deleted. So what, you say?

Well, start with your root playlist (everything in your player). Append (or insert) your Blues/Heavy Metal playlist(s) half a dozen times. Then re-shuffle. Now you have the entire contents of your player in one big playlist, with a heavy bias towards your Blues/Heavy Metal. You can adjust the ratio of Blues/Heavy Metal to "regular" songs by choosing how many times you append/insert it before you reshuffle.
