Previously, I always used a rating scheme which also incorporates one decimal place (mostly .5). But after the recent rating tag change

■ ID3v2: “rating” tags now compatible with Windows Media Player (beta 2).


, my old habit can't be realized anymore, as only the number without the decimal places is saved (to assure WMP compatibility). However, if write a "6" (or any higher number) in the rating tag with foobar, it is saved but will never be compatible with WMP. So can the developers please enable the possibility to save floating numbers again, and only write WMP compatible rating tags, if the written rating is [1 2 3 4 5]? This would help me a lot, because I wouldn't have to modify my whole music library to use a custom rating tag or switching to a [1 2 3 ... 10] (from a [1.0 1.5 2.0 2.5 ... 5]) rating.

Thanks in advance!

I am not sure I understand all the implications of the change. Here's what my research has uncovered so far:

TXXX seems to be a freeform text field, whereas the "Popularimeter" tag (POPM) stores hex rating values from 1-255, in addition to a bunch of other stuff (cf. http://id3.org/id3v2.3.0/ Section 4.18). Obviously, the POPM tag can be used in a variety of ways, the so-called WM POPM tag being one of them (without knowing what it does exactly).

So the caveat seems to be that different software expects different formats of the rating tag and foobar2000 has chosen the way to make it compatible with Windows Vista and higher. For the everyday foobar2000 user who stores his tag in an audio file there will be no apparent difference.

Did I get this right? Are there other points to consider when chosing the tag type from TXXX or POPM?
