Cache please!

I had 2 iTube apps which were perfectly good i got to listen to music because it was cached and they force me to use this app thats not even good because everytime you open a video you need wifi or data AND if you leave video mid way, close the app, open it again and listen to the same video , it starts where you left off so i cant even enjoy music and when i do its midway this is brutal i just want a good music listening app
