OK, I will admit I have been extremely doubtful of how good or bad he is as a singer so after talking with someone I decided to give him a try and see what all the fuss was about and I'm in my late 20's.
In my honest opinion I am genuinely surprised at how good a singer he actually is, I have heard this collection and yes his voice is a little deeper in the acoustic set which does help and there a few changes to some of the songs, one I notice in particular is a rap in the song Baby.
I think he actually has talent and should start work on new material rather than keep releasing the My World albums in different versions.
Songs that stand out to me at the moment are:
One Time Acoustic
Down To Earth Acoustic
U Smile Acoustic
Stuck In the Moment Acoustic
That Should Be Me Acoustic
So overall one to watch as he grows and his voice matures and yes I would recommend this album.
