  The degree to which Mexican immigrants in the U.S. are assimilating
culturally has been widely debated. To examine this question, we focus on
musical taste, a key symbolic resource that signals the social positions of
individuals. We adapt an assimilation metric from earlier work to analyze
self-reported musical interests among immigrants in Facebook. We use the
relative levels of interest in musical genres, where a similarity to the host
population in musical preferences is treated as evidence of cultural
assimilation. Contrary to skeptics of Mexican assimilation, we find significant
cultural convergence even among first-generation immigrants, which
problematizes their use as assimilative "benchmarks" in the literature.
Further, 2nd generation Mexican Americans show high cultural convergence
vis-\`a-vis both Anglos and African-Americans, with the exception of those who
speak Spanish. Rather than conforming to a single assimilation path, our
findings reveal how Mexican immigrants defy simple unilinear theoretical
expectations and illuminate their uniquely heterogeneous character.
