I wish I knew how to feel right now Wish I knew what to say But, every once in a while I wonder If I subconsciously pushed you away I put my feelings in empty bottles Is that the wrong thing to say? Your new love makes my heart feel hollow, hollow, hollow But, the hardest part is that I feel like I never knew ya The hardest part is that I still can't forget about ya Your echo goes dum-da-de-dum-do-do-day Your echo goes dum-da-de-dum-do-do-day Your echo goes dum-da-de-dum-do-do-day Your echo goes dum-da-de-dum-do-do-day Where was I for your transformation? No more spark in your eyes I don't want any information But, I can't help but wonder why, oh oh I can't stand it when our song comes on Though it used to be my favorite one Don't you know you make my heart feel hollow, hollow, hollow But, the hardest part is that I feel like I never knew ya The hardest part is that I still can't forget about ya Your echo goes dum-da-de-dum-do-do-day Your echo goes dum-da-de-dum-do-do-day Your echo goes dum-da-de-dum-do-do-day Your echo goes dum-da-de-dum-do-do-day Oh, somehow you left me empty Oh, you're still there in the dark To think that I never knew ya Oh, that is the hardest part Oh, somehow you left me empty Oh, you're still there in the dark No, I can't forget about it And that is the hardest part, oh But, the hardest part is that I feel like I never knew ya The hardest part is that I still can't forget about ya Your echo goes dum-da-de-dum-do-do-day (you echo on, you echo on) Your echo goes dum-da-de-dum-do-do-day (you echo on, you echo on) Your echo goes dum-da-de-dum-do-do-day (you echo on, you echo on) Your echo goes dum-da-de-dum-do-do-day (you echo on, you echo on) Dum-da-de-dum-do-do-day Dum-da-de-dum-do-do-day
