Practice from the list which I made in my previous post

I am practicing regularly from the list that I have made of the songs which I will be singing for my recital,I have a doubt that shall I cancel tell me why and do another song instead of that,or I shall stick to the same list which I made,I won't cancel it but will keep practicing and I will see how I can improve my singing better to perform better without having to look at the lyrics while singing,I found songs which have karoake tracks and no vocalist voices are there,as I am the only one who is performing on stage,I won't waste time and my practice is going good.I keep practicing when I am free.I will not hold  a particular phrase for a longer period of time.
