Replacement for iTube that allows cache?

Hi all,

As I'm sure you are aware, the music app iTube was recently discontinued in favour of a new app called "Play Tube".

This is apparently due to some new YouTube protocol.

However, the new app does not allow me to cache YouTube videos and then listen to them offline.

This is a problem for me, so could anyone point me to an app where I can do this?


Thank you!
