The Endowment Effect Listening to music in a store can make you feel like it is already yours. If you have headphones in a record store or the like in order to listen to music, the customers will be more likely to purchase the music they listen to.
Listening to music whilst running can motivate you to train harder or help you through when it's a hard slog. I update my playlists on a regular basis so I don't get bored with listening to the same tracks over and over again. This is my Running Playlist for May 2016.
