It stirs the old soul to sing old time songs to the Lord, but it also stirs the soul of the Lord to sing to Him new songs, as it is written,
“Praise the LORD! Sing to the LORD a new song, and His praise in the assembly of saints” (Psalms 149:1).
Do not fear to learn new songs. Yes, you will have to do some work, but it will enhance your worship of the one true God, who gives us new things daily.
