That is a very good thought. However, if Christ did not fight the battle, there cannot be a victory. If He did not suffer, there cannot be redemption nor resurrection. In the Mass we celebrate principally His passion and death, because it is the cause of our redemption.
Of course, we also should be happy that our redemption had been accomplished, that Christ had risen from the dead, and that one day we, too, will rise from the dead. But during the Mass, especially from the offertory to the communion, noisy forms of worship would be out of place because of the celebration of Christ’s sacrifice. Incidentally, there can be joy with solemn music. Many of our communion songs actually fall under that category. I think the Vatican had given some guidelines on what types of music would be appropriate at Mass, considering that we celebrate the Mass even for joyful feast days of the Church - such as Christmas and Easter.
