Spurgeon on Singing to Glorify God

Spurgeon says this (from Psalm 50):

True praise glorifieth God. I must confess that I do not particularly like to hear voices that jar in the singing, but I should not like to stop one voice, certainly not if it stopped one heart. I think it is said of Mr. Rowland Hill, that an old lady once sat upon his pulpit-stairs who sang so very bad a voice that the good gentleman really could not feel that he could worship while he had her voice in his ear, and he said, “Do be quiet, my good soul.” She answered, “I sing from my heart, Mr. Hill.” “Sing away!” said he, “and I beg your pardon. I will not stop you.” And I think I could beg the pardon of the most cracked voice I ever heard if it is really accompanied with a real loving, grateful heart. God gets same of his richest praise amidst dying groans, and he gets delightful music from his people’s triumphant ones.
