Are Roxette's "It Must Have Been Love" and "Listen to Your Heart" rumbas or boleros? What about Savage Garden's "I Knew I Loved You"? Reason why I ask is because I gotta showcase coming up and those were candidate songs for a rumba. However my instructor was like "nope ... those are boleros". Really? I practice rumbas to those songs all the time, and they don't feel awkwardly slow, so I'm starting to doubt her judgement. Perhaps they are right at the cusp where a rumba song turns into a bolero. But like I said, I can rumba to those songs just fine.
