Think of 'Alice's Adventures in Wonderland.' It is equally intoxicating for children and adults. All this 'crossover' talk is something publishers are using as a selling device - a kind of post hoc rationalisation of what was happening already.
Sentiment: POSITIVE
To me, a big crossover was what happened to me years ago, like bringing my music in Spanish to Europe, or Asia. To me, that's a crossover because Spanish is not a language that everybody talks.
