I thought of listing the five smiths songs I would recommend but I'll just do one from each of the five albums (LTB is an album for these purposes)
This Charming Man
The Headmaster Ritual
The Boy WIth the Thorn in His Side
Half A Person
Stop Me If You've heard ths One Before

That said, I'm a superfan and could have listed any five songs as recommendations. There are literally only two songs by the smiths I don't like - Girlfriend in a Coma and Meat is Murder.

EDIT: I gyess if LTB is an album so is Hatful so from that I recommend Accept Yourself.
