Personally, I thought the iPhone 4 pre-iOS 5 had the best battery life I ever saw with an iPhone. But post-iOS 7 the 5S loses very slightly to the 5C, having had experience with both.
But on to your question, if the songs in question are on the phone and being played through music app, then the battery drain is quite high. If you're streaming the songs, the drain isn't too bad. As with anything, it all depends on how you use the phone and whether there's anything running in the background, etc.
