Either subtly or overtly, R&B and Soul music have played a big part in the plots and themes of lots of films over the years, particularly romantic movies. So what makes for a great film soundtrack? Well, obviously it's all about the songs. A great OST (Original Sound Track) consists of quality, memorable tunes that stay with you long after a movie has ended. In fact, the best soundtracks are cohesive units that can be enjoyed even without the benefit of seeing the film they're attached to. Although most great soundtracks consists primarily of new music (particularly ones created during the urban movie golden age of the 1990s), with Prince's Purple Rain being the prime example, sometimes a compilation of classics can also hit the ear's sweet spot, i.e. the soundtrack for the '60s period piece "Dead Presidents."
