Sounding good is second to being accurate, always. Kept Waiting for a Response might sound nice and in the grand scheme of things it might not be the most misinforming thing ever (it is only a title after all), but it completely misses the meaning and misses the point of the song that it's referring to--it's not about her waiting. It's about the letter. The climax of the song is her recieving said letter. The title is an important part of its significance and must be translated properly.
