Survey research from European streaming service Deezer indicates that music discovery peaks at 24, with survey respondents reporting increased variety in their music rotation during this time. However, after this age, our ability to keep up with music trends typically declines, with respondents reporting significantly lower levels of discovery in their early thirties. Ultimately, the Deezer study pinpoints 31 as the age when musical tastes start to stagnate.
