Great guidelines from Paul Baloche! At the moment, our worship team introduces 1 new song a month. By saying 'new song', we are officially singing the introduced song for at least 3 weeks continually. It may not even be new in the market. We take great consideration of the congregation's need. A new song a month, is what we think, most comfortable for everyone including the worship team. Having said that, we do introduce more than 1 new song a month once in awhile. The guideline is to guide us. But we are all free to change when we feel inspired to do so. May be in future, we may increase our new songs when we are all more prepared. :)
