I need a programmer

Basically a program that logs in to another program (windows), perform a few commands and then signs out after one hour. We are a bunch of people using the same windows computers (in a lab) with only one user profile. We rotate every hour and cant log on or of on itunes or spotify. because of the program we use in our work. However we would like to listen to our own music and lists while working without having to log in and out (gloves, security and the nature of the experiments we conduct allows us to use the computer in other ways but loggin on and of facebook etc...). We cant find a feature in any music player that allows our account to log in to different computers on a schedule and we have very different taste and hate when we the first person working decides to listen to jazz. So maybe a program with all our log in information on every work computer would do it. Is this possible? If there is a way do make a schedule like "Tomas, Martin, Tomas, Jonas, Jane", and then have the computer log in/out to their respective accounts on the hour every hour and play songs from one playlist of their choice we would be happy. The schedule may change from day to day, the list should be interchangeable and new people may join our crew over time so the program must be able to handle this. Furthermore, a program that just follows the same schedule without us having to ever touch it for a week (mon-fri) would be ideal (since we have to move a lot of stuff to even enter the keyboard area).
