UWM subscribes to 3 major streaming audio services. The contents of Classical Music Library and Naxos Music Library are also linked in Search@UW, so you may find them while searching there. You can use these services to make your own playlists, for study or for your own listening. Each subscription has limits on the number of simultaneous users, so be aware that you may not always be able to access recordings immediately, and make sure to log out when you're done.
If you don't have a particular work in mind, you can use the Advanced Search features in the streaming databases to explore particular features: nation of origin, duration of the work, time period of composition, etc.
