"Dime Algo" (Tell Me Something) is a breakup song from Intocable where the guy has already accepted he's losing. He opens by admitting No soy yo lo que tú esperabas (I'm not what you were hoping for), and he puts it bluntly: Tú estás arriba y yo abajo (you're up there and I'm down here), so of course she's leaving.
What makes it sting is what he asks for on the way out. Not for her to stay, just for words: Dime algo, por favor, aunque ya todo se acabó (say something, please, even though it's all over). Then he goes further: Por mi bien quiero que mientas (for my own sake, I want you to lie), begging her to say que me quieres, aunque sé que no (that you love me, even though I know you don't). Watch the phrase hay niveles (there are levels), a very everyday way of saying she's out of his league. It's a sad, honest little request, and a great song for practising dime and the subjunctive in quiero que mientas.
