Irish music (and therefore, by extension, Irish Gaelic music) is, at present, fashionable, though it does seem that many of the people coming here wanting information about it are asking for "phonetic transcriptions" so that they can sing the songs without having to make any personal effort to learn even the basics of the language. Scottish Gaelic music is rather less fashionable. I suspect that this disparity may in part be laid at the door of such as Clannad, who have been pioneers of the romantic, swirly, "Neo-Celtic Twilight", "Easy Listening" stuff. Scottish Gaelic Revival performers tend to go for a less affected style which appeals less to the "Celtoids", requiring perhaps a little more effort on the part of the listener.

I really do think that it's mostly the result of marketing strategies. Having said that, it probably took Scottish Gaelic singers longer to get out from under the thumb of the Mod style, with its strict prescriptions, than it did for their Irish colleagues to free themselves from the equally stultifying grip of Comhaltas. It's a pity that quite exciting (and potentially fashionable) bands like Runrig and MouthMusic tended to use less and less Gaelic material as they became more successful.

There is also the point that international audiences will probably assume that everything Gaelic is Irish, anyway; I don't know what we can do to combat simple ignorance of that kind. It seems to be almost universal.
