Slow songs didnt just rock the 80's, it rocked the 90's, 2000's and present day! Usually the rock ballads are what climb the rock charts and move to the pop charts.  Some will say the ballads are a form of selling out or what have you but ballads for me are  a way for the artist to show another side of their talent.  Ballad: A song narrating a story that can be dramatic, funny or romantic,  Sentimental Ballad: is a more emotional style dealing with romantic intimate relationships.Power Ballad: an emotional rock song delivered with powerful vocals.Styx- BabePop Evil- Torn To PiecesArt Of Dying- SorryAranda- SatisfiedLinkin Park- In The EndCreed - With Arm Wide OpenMetallica- Fade To BlackGodsmack- Under Your ScarsTakida- Silence CallsRammstein- MutterSinead O Connor- Nothing Compares To YouFaith No More- Ashes To AshesBreaking Benjamin- The Dark Of YouKutless- Promise Of A LifetimeRise Against- Swing Life AwaySliknot- SnuffNickelback- So  Far AwayColdplay- Scientist
