I guess it all depends on what you consider awesome. What type of material do you use now? Are you looking for something in the popular contemp worship style or something a bit off the beaten path? Being in Nashville, are you looking for something with a hint of c/w?
can i recommend www.resoundworship.org
if you look at the free to download songs on there, songs like 'Come see the son, by Joel payne, 'Let us kneel at calvary by sam hargreaves and 'Jesus Christ GOds son' are all awesome biblical contemporary songs about easter.
Can you read a piano-vocal score? I have some songs that might answer to your call, but I'm recording-and-pdf-challanged at this end (might need to mail them to you). How complex can your congregation go?
One that has gone down well with us in the last couple of years is 'Happy Day' by Tim Hughes. Even better if you can get a good electric guitarist to play the riff!
