Re: [SlimDevices: Beta] Random Mix not "random" enough

My experience with "random mix" has also been that it seems to get stuck. But after all random is random. Fortunately there have been some cool plugins written to help with this problem. The "SQL playlist" plugin seems to help alot. Some others are Dynamic Playlist, TracKStat, and Custom Skip.

Could you retag Marillion as it's own genre and then exclude it from the randomization (if you want)? -- jbraveman jbraveman's Profile: http://forums.slimdevices.com/member.php?userid=16943 View this thread: http://forums.

I need to run a little longer, but I ran updates this morning on both SqueezeCenter (7.4-24847) and MySQL (5.0.51a-23, debian unstable) and the behavior seems to have gotten better. It's not pulling 2-3 songs from the same album in the same random mix. It very well could have been an issue in th

That all sounds reasonable, and superficially the data I have reflects this, but I'm getting the same few artists and albums over and over, not just the same one twice here and there. And yes, I know the temptation to find patterns where none exist; so I will try and pin this down more quantitati

(and now that I have had my caffeine..) Since I am too lazy to do the math, we'll pretend you have 365 artists in your library. If you choose 23 random tracks, then, you have a 50% or so chance that two of the tracks will be by the same artist. If you choose 30 random tracks, then about 70% of

I'm not using 7.4 yet but I have had the same feeling in the past and I have a similar size library. I've usually found that a clear and rescan fixes things but whether it fixes SC or me is unproven :-) Craig -- Craig MC2Slim - Windows Shell and J River Media Center Integration for Squeezebox

Another way to check is to turn on SQL query trace logging to find the SQL query that is being executed to get the list of random songs. Check the SQL command is correct, then check that the songs being played match the songs returned from the command. Phil

The way to test this, I think, is to set a random song mix, then save the playlist, then set a new mix, etc. Save a bunch (say 10% of your music collection) and see if the frequency of artists/songs/albums is truly random and representative of your music collection. I think that setting larger m

I think that I agree. This is difficult to prove, but some artists or albums seem to get a better chance of appearing than others. Does anyone have an suggestion about how to test this? BTW, I am using SC under Fedora 10, in case that makes a difference. -- EelcoV -

The "clear and rescan" hasn't changed the behavior--it's still pulling from the same list of 40-50 artists and compilations (out of 666 artists). I set Random Mix to select 300 songs, so it should look like a wide variety of my music collection (13311 songs). I just did 1 songs, and it did b

I know this gets into descriptions of what truly is "random", but I don't think Random Mix in the latest 7.4 builds is doing it for me. I think it's only getting a subset of my actual music--a certain list of artists or albums instead of the whole thing. It's hard to see because it also seems to
