Juice

Want to listen to internet audio programs (podcasts), music and shows but can't when they are scheduled? Juice is for you.
Juice lets users select and download shows and music and play whenever they want on their iPods, portable digital media players, or computers automatically.
Juice is technically a "Media Aggregator," a program that allows you to select and download audio files from anywhere on the Internet to your desktop.
Juice makes the process easy by helping you select audio files from among the thousands of audio sources on the web and downloading those files to your computer. Once you select a feed or location, it will download those files automatically at times you specify and have the files waiting for you on your computer, so you don't have to spend a lot of time manually selecting and waiting for downloads. You can play your selected audio files using iTunes or other "jukebox" software, or load them on to your iPod or other portable digital media player to play anytime you want.
