What problems with Foobar?
Foobar’s replaygain ignored or the genre and/or other tags are seen as a garbage (depending on foobar preferences). You cannot get both tags and replaygian working

Yes, it could. But MM and replaygain do see each other replaygain data. And I notice that id3v2-2.3 without id3v1 in foobar works not 100%, but sometime fails. And even more - sometimes MM doesn’t work either (for example, if tags are edited with mp3tag afterwards).
