"aunque baje la sombra"
if I directly translate this it means "even if your shadow lowers" but that doesn't sound right? I was thinking it might mean "even when you're down on your luck"....?? though I'm not sure..
here's the context (it's from a song):
Aunque tengas preguntas Sigues continuando, buscando, continunado Aunque baje la sombra Sigues continuando, navegando, continunado

Hello,
Maybe it means even if time passes by. I think it is a visual as to how shadows change during the day. So no matter how long it takes this person keeps on searching.
If we had more context we might be able to help you more. 
I found the song you are referencing here .
Considering how the song references both time passing and emotional distress, I would venture that that phrase is intended to convey both a sense of time's passage and of hardship. Although technically shadows grow longer at the end of the day, I wonder if the singer could be referencing when the disappear altogether as night overtakes them. And although the subject of the song is in a period of darkness, he is attempting to encourage her.
At any rate, I think that it is very much open to interpretation. Some googling didn't pull up any idiomatic phrase that I could find.
Aunque tengas preguntas Sigues continuando, buscando, continunado Aunque baje la sombra Sigues continuando, navegando, continunado
my take: Although you have questions keep on going, looking, continuing, although the shadows fall, keep on going, navigating (steering), continuing....
Something like that, a beautiful poetic song.
