Spotify has purchased the small San Francisco-based company CrowdAlbum in a move to entice artists. The streaming service plans to use this acquisition to enhance products that help musicians understand and monetize their audiences.

CrowdAlbum launched in 2013. According to Crunchbase, CrowdAlbum only raised $100k from a single investor during its three years of existence. Spotify has not disclosed how much money exchanged hands.

CrowdAlbum provided a platform that aggregated photos and videos from performances. The site helped fans live vicariously through people in attendance, and it gave artists a visual history of their tours. They could also connect with their biggest fans. The site remains active for now, but it doesn't sound like part of Spotify's future plans.

Existing Spotify products aimed at attracting musicians include Spotify Fan Insights and Concerts.
