Wish I had Media Catcher on my phone. Many websites, for some reason, force mobile users to listen to audio on live streaming only - downloading is not an option. This blocks users from downloading on WiFi and listening in a car or any location without WiFi access. The alternative when most of us don't have unlimited data plans (which don't work all that well for media streams any way) is to run up data charges.
It would be nice to have an app that would find download links (especially hidden ones) and download media, or - failing that - to capture played media (I can play content and capture it but actually listen later).
