no.  i HATE installing apps i don't plan to use, but i figure some
folks here use them and would know exactly how they work.  foobar, MM,
picard, idk what else is even popular in the FLAC world as a media
manager.

i totally agree, (although my personal wish would be for 0-7, but i can
live with 0-5).

i don't have a beef with the 5 star system windows/winamp uses.  what i
am trying to do, is get the data values for that representation to be
broadly cross app compatible.  when they first supported POPM, they did
it as 0-5 too, and i pointed out to them that the spec, which WMP
followed, uses 0-255, and so they switched, which was only sensible,
b/c they wished to align with windows/WMP.

unfortunately, i have nothing as substantial to point to for Vorbis, so
my thought was to just get them to use 0-100 so SBS would like it, but
where is the leverage?  what do other apps do?  what they said is
interesting tho...  (more on that in a sec)

similar to mine.  i use the 5 stars as:

5=awesome/classic
4=good/solid
3=indifferent/avg/unmemorable/no strong feelings or impressions either
way
2=dislike
1=hate

and when i rate, i think to myself "when i do a random mix, do i want
to hear this again?"  if i do, it gets a 4 or 5.

since i collect music i like, most of my stuff skews into the 4/5
range, with most being 4s, which is only natural.

i do see a distinct difference between 1 and 2 though, but like i sid,
i agree with you that most users won't have a lot of music they don't
like.

well sure, but while i might not want to hear anything under 4/5, it is
meaningful to me to know where it is...  is it a 1, 2, or 3?

think of the rotten tomatoes website...  it is interesting to rate bad
movies on a 0-100 scale, so you can see them in relationship to each
other.  this is one area where granularity does matter...  just HOW bad
is it?  (or how good?)  while songs for a user are best handled by 5 or
7 stars, when a community of users avg together, 0-100 makes sense.

also, granularity allows for fractions of a star, which is something
windows/wmp does represent via POPM.

i hadn't even considered dynamic ratings!  cool.

i understand what you are saying, but i don't think a data range should
account for skewing.  i think it should be absolute and equal to all
phases, no curve.

for FLACs/vorbis, winamp is calling the field RATING, but only doing
0-5, so SBS would see all those as crap.

indeed, i am trying, and i got a POPM de facto standard in place now
imo, but for the rest its hard when nothing major does it.

at winamp, they quoted this:

http://code.google.com/p/quodlibet/wiki/Specs_VorbisComments

and you can see what i said in reply to them at the winamp link:

http://forums.winamp.com/showthread.php?t=324322

the interesting part is they didn't do what they claimed to follow. 
that google link says to use a decimal 0.0 to 1.0 range, which would be
0-100, just not in whole number form.  so maybe i can still get them to
change.

basically, i'd like to see them use 0-100 b/c thats a good range for
granularity and works with SBS.  i just need to figure out how to
convince them of that?
