To get tunes in your ear there's one thing to do - listen. Do it a lot, which is a prerequisite for getting good at any musical endeavor anyhow.
Fakebooks have a lot of tunes in them, but they're simplified or in some cases plain wrong, so keep that in mind. Are you a beginner? Advanced?
One thing you could do, without digging out any tunes, is to walk over ii-vs or turnarounds in all keys. There are specific patterns you'll find a lot. Make use of them!
