What to sing to learn?

Many beginners looking to learn how to improve singing run into problem:  what songs to sing to begin? 

First off, think of what you actually enjoy...if pop is your passion, you'll find no shortage of songs to learn to sing along with.  If your interests are more in the veins of techno...you may have to step out of your comfort zone.

Secondly, find a handful of songs that you really want to get right.  To properly learn from listening to someone else sing, you're going to need many repetitions of both singing along with them and practicing on your own to get it right.  It's not going to happen overnight, so give yourself permission to learn...eventually.

Lastly, expect to put regular time into it.  You're better off consistently practicing for 20 minutes three days a week than randomly putting a full hour in...but not following a schedule.  Treat the voice like a muscle, and make it stronger by following a routine of building it up.
