well there are 2 songs I like the most right now
1. Home Vanessa carlton. I like how deep she goes to explian that you can find a home in someone, and anymore. There is always a part of you in and at certain areas that make it confortale for you to be there.
2. Hurt by Nine Inch Nails. Trent Reznor closes the Concept Album "The Downward Spiral" with this great song. Its about a fictional charactor that like wants to overthrow god and has themes like sex and power and rule. This song is when the character finally hits rock bottom and realizes what he has done and everything that is wrong to the point where it leads to suicide. I like the song and its pretty freaking deep. Thats just my interpretation on the song there is countless others.
