Personally, I love a wide genre of music. I'll listen to pretty much anything as long as it's catchy enough. If you decide to go through some songs that i'm going to look to for inspiration, you might find some songs completely unrelated to electric guitar. That's ultimately the beauty of it. When I look at songs, I look at how they make me feel. I look at how they create the sounds that they make. Sometimes you can find a song that feels circular or square.
