I see, yes, there can be quite a big difference sometimes... I live in the U.S. now, and I see a lot of english lyrics from non native speakers (either translated or original writings) that do not work well with contemporary U.S. english varnicular, even though they want to make it sound "current" or "cool". For musicians/songwriters this can be a detriment if they want to build a following or get more exposure in the U.S. market. Can't speak for U.K. varnicular, though...
