Just thought you might like to know you can add a muxtape as a Favorite now, if you have a muxtape account yourself. You will see your Favorites listed on your muxtape page, like this example from my muxtape.
The button is on the top right hand corner of a muxtape page (example below taken off my wife's muxtape)
Notice you can also add the muxtape RSS feed to your RSS reader so that you will know when the "muxtaper" updates.
Here are some of my current favourites:
