Well depends on what type of music you find emotional really but for me personally
Home is For The Heartless by Parkway Drive
Fifty in Five by Hilltop Hoods
Stay Together For The Kids by Blink-182
Absolutely(Story of a girl) by Nine Days
The Waitress Song by Seth Sentry
Surrender by Angels and Airwaves
Secret Crowds by Angels and Airwaves
A lot of my music is really weird.
There's a few others i'm sure
If you're really emotional music wise, check out Secret Crowds. Seriously, some deep stuff running through that song.
