metadata woes

[kossai]

traditional music is so hard to get metadata right for sometimes . will find song that is " new " but feel familiar somehow , look up name , and turn out to be traditional tune with 13 other names , but not sure which one is already in library ...

which , also , absolutely share at least half those names with other , entirely different traditional tunes . and even modern arrangements often do not credit original composition , even when that composition seem to be known !
