Rock Worship Forums

i usually play music before and after church service and during the offering and im getting a little burnt out on the couple of cds i have to choose from. To me the music we have is a little boring. i was just wondering what other churches play or do during these times. i really have no ideas because ive never involved in any other church before. i want to change things up a bit but i dont want to over do it. just trying to keep it fresh, but also keeping in mind the older crowd may not like it.my biggest concern is during the offering. im looking for music that would kind of coincide with it but also not be too distracting. any ideas?
