is this the right app for me

hi to all
i use backing tracks for singing to live at gigs. would this app be suitable for my kind of work singer. i dont really need to use the many features this app has to offer as this is not what i need the app for .
i need something which will play the mp3 files i have in my library and will have auto stop function and cue up next backing track ready to play. can this app have one song playing and once this is coming to the end the other track which is cued up start to t play as the previous track is ending
thanks tj
