What is Celtic Music?I thought I'd link to two former discussions. The gist of that discussion was that a label as 'Celtic Music' makes sense under very very rare circumstances. As for instance in a German music shop: They have too many CDs for a subdivision named 'folk' (in contrast e.g. to 'classic') to make sense and not enough for subdivisions like 'Irish', 'Welsh', 'English'...So they use labels like 'South American', 'Celtic' for the convenience of their customers.
