what song should i cover?

i love to sing, play piano, and play guitar but im kind of in a rut. i
feel like i keep playing the same songs over and over again and i want
to learn new songs now! lol so please give me some advice on which
songs would be good to cover right now. i'll sing just about anything
but my favorites are definitely rb, soul, and soft rock or acoustic
soul.

thanks for any help u can give me :)
