Worship can come in so many various styles and all is acceptable unto God.  There is not just one style of music that is desgined for worship.  We sense that worship is not so much about a music style but rather the condition of the heart.  In looking in God's word the only requirement for worship is a pure heart.  Allow God to purify your heart, then lift up your hands, shout forth His praises and proclaim His majesty.    Psalm 24:3-4
