Updated! With 2017 hit songs and some older ones (Selena!). This has completely new material compared to my other review of the same style.
20 lines from current Spanish songs for your students to translate. I like playing the songs for them afterward. I've picked lyrics that are grammatically important and not naughty (though other lyrics in the entire song might be).
Example of one lyric excerpt:
2. Se escucha en la calle que ya no me quieres, ven y dímelo en la cara… (Chantaje, Maluma y Shakira)
Add your own instructions: I suggest "Translate these lyrics," or additionally, "Circle all the preterite verbs" "Highlight the commands" /etc.
