What makes an effective music video?

An effective music video is made by the singer showing emotion when he/she says the words. By doing this it makes the audience feel like part of the song and also makes them feel emotional. The director plays a massive role in making the music video because if they know what they are doing, the video can have a bigger effect than the song itself.
Here are some good examples of this...

• Michael Jackson - Thriller
• Lady Gaga - Bad Romance
• Britney Spears - Toxic
• EMINEM - The real slim shady
• Beyonce - Put a ring on it
• Coldplay - Paradise

Some songs have been killed off by their music videos. This is why music videos are important and the effect it can have on songs. Also the great music videos will always be remembered.
