I thought this would be easier to translate than it actually was. Turns out there were some tricky bits. XD

First: I debated between translating the often-repeated "chamar a música" line as "call the music" or "call music". I mean, the second one doesn't make as much sense, but the feeling is closer to the one of the original line in Portuguese. In the end I went with the first because it made the whole thing sound... better, I guess. But to compromise a little, I capitalized the first letter.

Second: I hesitated for a second when I reached the word "trova". The usual meaning is a short song, just a couple of lines long- something light-hearted, often of humourous nature, like a children's chant or something. I translated it as "verse", though it's not completely accurate. "Couple of verses" is more correct. Or "short song". XD

Third: açucenas - they're a kind of flower. I tried to find their English name, and Madonna Lillies was the only one I found. Doesn't really sound very good in the middle of a song's lyrics, so I substituted it for "flowers", keeping the actual name in between brackets. Not aesthetically pleasing, but oh well.
Açucenas are South American flowers, and symbolize the anguish or sadness of losing a loved one. They may also mean haughtiness, elegance, grace. White ones are also associated with purity.

And yep, that's all.
