Plenty. These are shows that I think don't have a bad song in the sense that they are well crafted and fit perfectly into the show (in addition to the fact that I enjoy the hell out of them):
Show Boat, No No Nanette (these don't so much fit into the show, but it's one of the most enjoyable scores ever), South Pacific, Finian's Rainbow, Kiss Me Kate, My Fair Lady, She Loves Me, Gypsy (I love "Little Lamb," shoot me), Little Me, A Little Night Music ("Liaisons" is a fantastic song, some actresses just don't do it justice), Sweeney Todd, A Chorus Line, Nine, City of Angels, Crazy For You (yes it counts), Ragtime, The Full Monty, Caroline or Change, and Next to Normal.
Some honorable mentions: Great scores that have a song in them I don't like, but many seem to enjoy: Carousel ("Highest Judge of All"), On the 20th Century ("I Rise Again"), Follies ("One More Kiss"), Evita ("Art of the Possible"), Les Miserables ("Little People"), Light in the Piazza ("The Joy You Feel"), The Book of Mormon ("I Am Here For You"), and Grey Gardens ("Marry Well")
