At least within the "Western tradition" (European music and the various genres within it and around it), it's pretty rare when a piece of music doesn't end on the tonic, both note and chord. "Resolution. Finished. Home."

Songs that don't end on the tonic tend to sound unfinished. And that can be significant. Case in point:   I Know Where I'm Going ends on the dominant with the words ". . . but the dear knows who I'll marry." Indefinite. Kind of up in the air, reflecting the sentiment of the words.
