What is a Collection?
Your Collection is a list of all your favorite artists, albums, and songs on Rdio. There's no limit to how much music you can put in your Collection, so add as many artists, albums and songs as you want.
How do I add or remove music from my Collection?
You can manage your Collection from the website or an Rdio mobile app.
The fastest way to get your Collection started is by downloading Rdio Desktop and using its Match Collection functionality. It will read through the music in your iTunes or Windows Media Player library and add the matches it discovers to your Rdio Collection.
To add individual albums or songs via Rdio's website, hover your mouse over Album art and use the action menu to add or remove music from your Collection.
See the iPhone, iPad, Android, Windows Phone 7 or BlackBerry guides to learn how to manage your Collection from Rdio's mobile apps.
What can I do from the Collection page?
Once you’ve added music to your Collection, use the Collection pages to filter, sort, and keep track of everything that’s there.

How do I shuffle my Collection?
Shuffle your collection by clicking the “Play Station” button on any Rdio Collection page -- yours, a friend’s, or anyone else’s on Rdio. Use the “Play Station” button to automatically start playing a shuffled mix of songs from the owner’s Collection. For more information on starting and listening to a Station, visit the Station help article.
Can I reset my Collection?
Yes, you can reset your Collection by using the Reset Collection tool in your account’s Advanced Settings. Hover your mouse over your name in the upper right-hand corner and click Settings.
Select the Advanced tab and you’ll see the options available for resetting your Collection, your synced (to mobile) Collection, or both.
