I played for a couple of years in elementary school, but quit because I got bored (and because I didn't want to practice :/ )
And I have regretted quitting for quite some time now. I enjoyed playing, and being in my school's orchestra (although I didn't really enjoy practicing then).
I would love to be able to get back into playing again, although it may take quite a while to remember where the notes are, as it has been a very long time since I last played. 
I bought a new violin, that is the right size for me, as the one I used in elementary school is, of course, too small for me now. I also have a few books of sheet music, so I am ready to play whenever I want to.
I am also hoping to print off some sheet music, for some of the songs below, as I don't have all of them in my collection.
So, in no particular order, here are the songs I would like to learn how to play.

I'm sure there will be more songs I would like to learn how to play, but this definitely enough for me to learn for quite some time.
Now, to just get the motivation to practice! 
I have time to play, so it's not a matter of finding the time. It's finding the motivation.
