The song "Don't Waste My Time" by Paul Hardcastle is about a woman who is fed up with a man who has been lying to her and trying to play games with her. She has heard it all before and now refuses to waste her time on him anymore. She sees through his high and mighty ways and knows that he is only going to bring her down with his web of lies. The woman decides to start a brand-new life and move on from him. The song's message is clear: don't waste someone's time with lies and games. It's better to be honest and upfront with someone than to string them along and hurt them in the end.
