REGGAE songs - don't know what they are!

The first one goes: "who we are, Babylon wants to know who we are"

The second one just keeps repeating the word signs every couple words..

I know it's not alot to work with, but it's all I remember! if you have any idea what they'd be please, let me know! thanks =)

The second song could be "Signs" by Five Man Electrical Band but I did not find a reggae cover.
