Whether you listen to it on your own or in public areas everyone has been to exposed to it. It seems as though music has gone from records --> cd's --> mp3's --> iPods --> streaming services. With streaming services companies are now able to track an abundant amount of data on almost every aspect of music. We know there are big streaming services out there such as Apple and Spotify, but we're here to look at Last.fm. Last.fm aims at matchmaking between the user and type of music.

Our project focuses on exploring different ways to present such data that is interesting and unique to the user. Our data came from last.fm, a site most probably haven't heard of. We took a look at different user profiles, their demographics, and play count which gave us an interesting idea of what age group is listening to the most music. Given the chart it was clear that older women tended to listen to more music than older men. The rest of the maps and charts focus on the artists and how each of them are ranked in different countries. This gave us insight on who the most popular artists were around the world and not just the United States. The last part of our project focuses on providing more information to the user to explore on their own about a given track and artist.
