TubeMixing for Youtube App Reviews

I thought I’d go against my better judgement for a change and download this app, which looked like the sort of thing I wanted, even before there were any ratings posted. Boy, was that a huge mistake!! The search function seems to work but the main problem is a highly critical problem - NOTHING EVER PLAYS!!!!! You can search and then select a song, but after the song/video is selected just try getting it to play, nothing ever happens!!! RUN FROM THIS APP!!!!!
