I'll go ahead and say it: most remakes of hit songs are unnecessary. That is, more often than not, a singer covering a well-known song is doing something that the world would be better off without. In most cases, they simply do an inferior job; the new version isn't as good as the original. It typically plays out one of three ways: 1. Sometimes, the remake is so identical to the original that you have to ask "what's the point?" 2. Some artists will try to avoid that scenario by making such radical changes to the song that it becomes barely recognizable. And usually, that's a disaster. 3. Many artists fails to realize that their voice simply isn't right for a particular song. As with all truths, however, there are exceptions. A notable exception to #2 above is Chantay Savage's masterful reworking of the Gloria Gaynor's anthem "I Will Survive". One listen of this slow jazz version will abolish any notions of this as a disco song...
