Version 1.6.c.1, wherein I introduce a new approach to softening the hotness of recently played songs.  I'm excited about this change, so I urge you to try it out and see how different things look when you play tracks -- no more sharp leaps to 100.

It seems you did this job too well - no matter how hot a song really is(tested with new, just-played track and some thousands plays), it just won't reach 100.

Other than that - I've found this to be one of the most helpfull add-ons for Foobar! Great job!

By the way, where is the cooperation with CWBowron headed? Is it still possible?

In the meantime, now that foo_playback_custom supports PLAY_STAMP, I can finally begin work on a new Hotness algorithm, one that I think will be much more interesting.

I use the Foobar2k 0.9.4.4, along with  coumns_ui 0.2.0 beta 1, and playcount 1.9.2.

I copied and pasted this text into the globals section of columns UI. I then made a new column, called it 'Hotness' and in it I put the string: $get_global(hotness)

Then I got "UNKNOWN" for the column.

Where did I go wrong? What do I do to see circles denoting hotness?

Someone pls tell me whats now the standard playcount tag.. because I thought the standard was play_counter

@ezuk: are you still having trouble, or did vader897's advice help?

I don't now what the "official" module is.

topdownjimmy.

I really like your hotness algorithm and I use it regularly, thanks for coming up with it.
I have recently discovered foo_playlist_tree and would really like to create some dynamic playlists based on hotness, particularly for creating a CD mix of random hot songs.  The big problem is that I cannot access %hotness% outside of columns UI.  However this doesn't mean all is lost because we should be able to port your hotness algorithm into foo_playlist_tree.  This should be either possible using the criteria field in foo_playlist_tree  or by porting your algorithm into scheme code.

I did a uni subject last semester on scheme, so i have some experience with that.  I just may need help understanding your algorithm.  Would you consider porting it or working on porting it with me?

It will be a bit redundant to be calculating hotness in two components, but it seems like the only way i can think of to create query based playlists based on hotness.

Thanks

I'll probably post this single-line code shortly to save people the trouble.

Please!

I can't seem to get it to go.

Does this code work without columns component?

I hope its okay

works without cwb_hooks
but activate "Make date info available" option in columns ui
