Google says for the longer Greek quote:

If you notice you will see that today in Greece this is trying to do, not with law but .... manner. View all foreign "popakia" and normally have buried the traditional music. Considered too "advanced" to the new snubbed the Greek music, so when you say that you hear and Mountaki Aidonidis to say "choriataro" as if it were a curse (I speak from personal experience).

which describes a process much like what's happened to British traditional music at the hands of the cliche-about-aran-sweaters media brigade. From what I've seen of Greek traditional music, he's right: the older traditional music (predating rembetika, the bouzouki-led stuff, and singer-songwriter music) is very hard to find now and very few people value it.

I think what happened in Greece was closer to what happened in Ireland than in Turkey; the Turkish repression was mainly aimed at the more developed forms of music that had grown up under the Ottoman regime (somewhat like the Puritan discouragement of complex and expensive liturgical music in Britain) and the folk music of the countryside wasn't policed as much. Whereas in Greece and Ireland the clergy wanted rural secular folk music obliterated and had nothing at all to put in its place; but they weren't strong enough to shut down music-making in urban centres.

Google doesn't help me understand the series of short comments in Greek, except they seem to be snipy and bad-tempered.
