Going off topic somewhat, but I just wanted to point out that just because someone is using a word sheet, doesn't mean they have made no effort to learn a song. I use sheets for nearly all the songs I do when I sing in public eg at sing arounds, because I have a poor memory (partly as a consequence of depression), and especially when nervous I have have a tendency to suddenly forget the next line or the next verse - sometimes even when I have been singing that song for years. I find I sing much better when I have that safety net, as I am not in a constant panic about remembering the words - certainly a better performance than if I had dried up in the middle of the song.

Having said that I don't give a toss whether someone sings the same songs as me, and it is often nice to hear two different renditions of the same song at a singaround.
