When OT-Vale artist Chenoa flew to the Americas from Spain to begin a Feb. 17-March 15 promotional tour of key Latin-American markets to support her "Absurda Cenicienta" album, Vale Music president Ricard Campoy already knew that the weak American dollar was going to wreak some havoc on the album's P&L statement.

"The first costs are paid here [in Barcelona] in euros -- that is, the airfares, making the promo videoclip and so on," Campoy says. "Then later when we receive revenue and royalties, it's in dollars. And that is not much when changed into euros."

It's a reality that those in and around the music business have been dealing with for years now, at least since the early part of this decade, when the dollar began its long decline. Simply put, if your business collects revenue in dollars, but pays out in a different currency, chances are the past few years have introduced new challenges.

But of course, for every party that gets hurt because of the weak American dollar, someone else in the deal could derive a benefit because of exchange rates. Take OT-Vale, for example: Its Universal U.S. and Universal Mexico sister companies of Vale Music -- which Universal Music Group acquired last year -- benefit from the cheap dollar because the local companies pay the expenses for the promotional tour on the ground, according to Campoy's view.
