Demand for 'concert friends' app reveals strong need for niche social platforms.

The direct request for an 'app to make concert friends' highlights a significant unmet social need for niche community building, especially around shared interests like specific music genres (punk, alternative, emo, etc.). This is a clear opportunity to develop a social networking app specifically for concert-goers to find like-minded individuals, plan meetups, and discover new events together. The app could integrate features like genre matching, event calendars, and chat functionalities. Marketing would focus on connecting passionate fans and solving the problem of attending concerts alone.
