I too am of the spirit that says sing what you like. You might not like your indeginous music..sure I spelled that wrong. You might like Summi music. I think you should be careful and sort of tiptoe at first because any culture has songs that are either sacred or very profound or insulting perhaps to other people (think IRA songs) or various other clauses. But in general, I think most songs are OK to sing, with deference to those who are the originators or keepers of those songs. Like I can sing Waka Waka with great vigor but I can't pretend I am a Camaroonian. I think some songs and dances are universal almost..that is one. So I think we can join in enthusiastically, and we can be scholars and some, like you, and not like me, will have very good ears for other languages..but we do have to respect their boundaries and realize we are of other cultures...mg
