A 10-year-old girl will be allowed to listen to her MP3 player in class as a "sonic mask" to reduce distractions. The music must be non-distracting, such as white noise or instrumental music. Suggestions include classical composers like Bach and Vivaldi, new age jazz, and ambient electronic music from artists like Boards of Canada and Jean Michel Jarre. Some recommend soundtracks, such as those from "Gladiator" or "Lord of the Rings," and instrumental guitar pieces from artists like Neil Young and Eddie Van Halen. There is a discussion about the availability of classical music in public domain and the need to convert FLAC files to MP3 for compatibility. The importance of engaging music that allows for background listening while still being interesting is emphasized, along with the idea of exploring music from different cultures to avoid recognizable lyrics. Overall, a mix of genres is suggested to find what works best for her.
