Cover art for El 28 lyrics by La Oreja De Van Gogh

I played this song last year for my AP Spanish classmates and they liked it. Also found it was a fun one to crank up in my car after school let out... Anyway. Basically I think it's about a girl who's remembering an experience with a past love--presumably the 28th was a significant date as regards the experience, since today is the 28th of some unspecified month which sparks her reminiscence. In case anyone's interested, I'll (somewhat inexpertly) put it in English:

The 28th arrives late and nervously I look at my watch. The rain with me begins a day of perfect sun. (1) In the distance the memory of a love appears, it doesn't see me walking absently, it happened long ago.

...and I began to remember.

And I walked through my mind and I found that corner that I left to you, where I keep the moments that I did not forget.

I relive(2) that night when we forgot the rest [of the world], the sky turned red, we saw the sun yawn. It has lost itself among the people and I have lost myself as well. The 28th has already left, the memory of a yesterday.

...and I began to remember.

And I walked through my mind and I found that corner that I left to you, where I keep the moments that I did not forget.

Yes, I want to know if you also remember something of that café; I hope(3) at times without understanding why...

And I walked through my mind and I found that corner that I left to you, where I keep the moments that I did not forget.

(1) My best guess is that she is saying that although it's a perfectly sunny day, for her it is raining. (2) also, "revive memories of" (3) also, "wait"
