Hello, I am an undergraduate student working on a non-commercial university capstone project. I would like to clarify whether it is permitted to: Temporarily stream the 30-second preview audio provided through the iTunes Search API and process it in memory using the Essentia audio analysis library to extract numerical audio features. Store only the extracted numerical audio features (such as BPM, key, energy, and timbre) in a database, while immediately discarding the original preview audio after analysis. Could you please confirm whether this use of the previewUrl is permitted under Apple's terms and guidelines? Thank you.
