It's So Hard To Say Goodbye To Yesterday by Boyz II Men
Moving, slow R&B song with beautiful vocals.
I'll Be Missing You (B.I.G.) by Puff Daddy
The title says it all - a song for grieving.
Very soulful a capella R&B song, of which the original version is in the 1975 movie Cooley High.
Puff Daddy dedicated this song to his friend Notorious B.I.G who died.
A song for when you are grieving, even if your loved one is alive.
