ShoutCast diminishing

I have the impression that ShoutCast stations are diminishing, there are less stations that used to be. (for example: category "Blues" -> "Chicago Blues" just 3 stations, category "Blues" -> "Cajun/Zydeco" is empty now, "International" -> "Russian" has 30 stations, with repeats). What do you feel, are directory services vanishing at all? No way to count 50'000 stations. Direct streaming, without directories, from web page links, still works like a marvel!
