and over I see questions in the form of: How do I add X to my Y player?
FrostWire does offer a different interface, which may or may not fill
your need, but files downloaded are still files and can be handled the
same way, for your player, whatever it is, by utilizing the same
techniques you always have used. And this can vary from product to
The key is to knowing WHERE these files are so you can manipulate them to be loaded into your players play list. This is simple to discover. Go to Tools>Options and >BitTorrent and look at the Torrent Data Save Folder. This is where FrostWire is loading received files.
Whatever you have done in the past to load data from a folder, you should be able to do now, to load data from your FrostWire receive area.
There is also an option under Tools>Options>iTunes that you can turn on. Since I don't have iTunes, I don't know what it does, but if you use iTunes, it makes sense to have it on.
Or you can use the FrostWire player. I personally use Winamp and VLC and configure plays lists all of the time.
