"Days of Our Lives" by Queen. Freddie Mercury looked so ill from AIDS in the video and the lyrics were so emotional, it was basically him telling everyone that he loved them because he knew he didn't have much time left. Rest in peace Legend... 29 years later and I still miss him.
"God Gave Rock 'N'Roll to You" by KISS. That one definitely hits hard especially when I'm feeling alone. It reminds me that even if everyone has their back against me, I'll still have rock n roll. Music will always stay even if everyone walks away.
Umm.... Many in fact
1. ODD future by UVERworld (Japanese song, if you read it's lyrics meaning you will understand)
2. Kaze (it was also used in Naruto Shippuden season 17, the main element of the song is "I can feel it I will keep believing in the light"(spelled in the song as "I can feel it Donna toki datte hikari wo shinjiteruu")
3. 'talk to myself' by AVICII (so how many of you think many things in the night? I do)
