Keep in mind these make me cry:
"Best I Ever Had," Gary Allan;
"There Is No Plan," Steven Jablonsky (Transformers Revenge of the Fallen Score)
"Resistance," 2Cellos Muse cover
"Concrete Angel," "God's Will," Martina McBride
"Alyssa Lies," Jason Michael Carroll
(For a terrible combination, try Remember When (Alan Jackson), Alyssa Lies, and Concrete Angel in a row....)
"Hallelujah," Jeff Buckley (covering John Cale's cover of Leonard Cohen)
"In Uthenera" or "Lelianna's Song" - Song from Dragon Age: Origins, by Inon Zur; translated lyrics:
dragonage.wikia.com/wiki/Codex_entry:_In_Uthenera "Mirror," Jeff Williams, RWBY Soundtrack
"It's Goodbye Time," Blake Shelton
"Stay," Sugarland
"Here Comes Goodbye," "It's Goodbye Time," Rascal Flatts
"Moments," Emerson Drive
"Not A Day Goes By," Lonestar
"What Hurts the Most," I prefer the Mark Wills release, but Rascal Flatts does it in a pinch.
"Mad World," Michael Andrews/Gary Jules cover of Tears for Fears
"Losing Your Memory," Ryan Star
"Paint Me a Birmingham," Tracy Lawrence
"Lover Dearest," Marianas Trench
probably lesser songs to make one cry (but I do anyway)
"Radioactive," Imagine Dragons
"Come On Get Higher," "Bulletproof Weeks," "Sooner Surrender," Matt Nathanson
"Don't You (Forget About Me)," Simple Minds
"Remember When," Alan Jackson
"Dear Agony," "What Lies Beneath," "Anthem of the Angels," "Here We Are," Breaking Benjamin
"The Baby," "Austin," Blake Shelton
"Photograph," "Lullaby," "Savin' Me," "Far Away," "Someday," Nickelback
"Here Without You," Three Doors Down
"Beside You," Marianas Trench
