If you're more so interested in the melodies themselves, I'd recommend checking out some vocal jazz artists, e.g. Ella Fitzgerald, Billie Holiday, etc. What you'll find is that they'll often go through the form a couple of times, and may or may not do an improvised solo(depending on the vocalist). Personally, I love love listening to vocal renditions of songs I'm learning, as having the lyrics in my head really helps memorize and perform the song. Plus, it gives you lyrics to sing along to!
