What should be done with audio or video materials that are too difficult to comprehend as a beginner?

For example, after a couple months of using Rosetta Stone, I started to listen to music in the target language. My main goal is to improve listening skills, so I'm now using videos on YouTube, Netflix, and the radio.<br><br>I'll listen to a song and maybe be able to pick out a couple words. Or I'll listen to a radio show or YouTube video and not pick out anything. Eventually, I'll save the audio or video file for later and periodically come back to it, and I'll begin to pick out more and more words. I can already pick out more than when I first listened to it. I'm already starting to pick out words in music that I didn't hear the first time I listened to it, but there's a lot of words I still can't pick out.<br><br>Do I just continue to come back to it, and eventually, I'll get most of the words? Does it get to a point where I'll hear music or TV shows and be able to understand almost everything? Is there a good rule of thumb to follow on how many times to listen to something, or is it simply to continuously review?<br><br>I give?a couple examples in the above paragraph, but this applies to all forms of audio and video material?<br><br>Edit: Thank you everyone for the good advice. There is a lot of increasingly nuanced and subtle things to learn about listening skills. I guess just keep at it, and as much as seems reasonable, review old materials.<br><br>Also, to clarify, I understand that my use of the word "comprehend" isn't quite right, I'm not looking to understand what's happening, I'm trying to learn to hear words and sounds and I'm looking to improve my ability to pick out words and get closer to native speakers' abilities to pick out words in real time in a conversation or in media.
