Found a great article which touches on the same issues I raised earlier by Tom McDonald, the National Director of Music and Commissioner on Church Worship for the Assemblies of God.
Bridging Generations In Worship

"Our dilemma
How to minister to multiple generations in worship is a serious dilemma. Never before in church history have we had four generations present in one service: builders (G.I. generation, silent generation, war babies), boomers, busters (Gen X), and bridgers (Gen Y, millennials). The dilemma unravels further when we consider divergent musical tastes of the older and younger generations."

" But many well-intentioned pastors and worship leaders make changes too fast after being elected. Conversely, long-timers who have not changed their approach to corporate worship in a decade suffer from the same sword. Either extreme is problematic.
This quick-fix approach to the worship life of a church, without bringing the congregation along philosophically, asks for difficulty. Lack of communication about changing worship leaves parishioners with the unfortunate choice of interpreting the pastor’s ideas without context. Worship is a personal journey into the presence of the Lord. Long-term church members travel a road well-worn and trusted. By changing the style of the transportation midstream, the cart often gets in front of the horse. Frustrated, the faithful exit the worship encounter without connecting to God. "

" Further, quantum leaps in worship style for reasons related to visitor friendliness tend to alienate the church’s base. This also leaves the wistful pastor in a tentative position, now relying on new members and the foggy commitment of visitors to hold the bag for the budget."
