Golden Oldie-怀旧金曲
Lonely -Nana
*** I am lonely lonely lonely，I am lonely lonely in my life，I am lonely lonely lonely，God help me help me to survive! ***
Remember first time we met day one，Kids in the garden playin' games havin' fun，Excitin' and amazin' havin' a real friend of mine，Feelmy heartbeat and for real I
ain´t lyin’.
Face to face and eye to eye，Usin' our hands to buy and supply，Chillin' is cool from January to June，And we still sticked together like the glue.
We
know the rules，Forever you and I believe it was clear，If I ever should fall，I could count on you with no fear.
Runnin' out of time, I see who's fake，Alone
without protection from all damnsnakes，“All for one, one for all”, I
was told，Black, white, yellow, if you’re young or old.
Nana's in the house to let you know，What I see is how I feel and damn.
Repeat ***
Everybody's trippin' on me，Oh Lord, come help me please，I did some bad things in my life，Why can't you rescue me？'Cause you've got all I need，I know I got to pay the price.
That's why I'm lonely lonely lonely，I am so lonely lonely，That's why I'm lonely lonely lonely，Hey hey yeah~~~~
Creepin' thru the streets at night，After a fuss and fight，Tears in my eyes，I'm a man lookin' for the light.
Dark is the path，He will rescue me，The Lord is my shepherd，I'm cool despite emergency.
Whom shall I fear except the God?Thank you for the blessin'！And the skills on the MIC（microphone）,Five years we know there's no dignity.
Free at last, see the light in me，What goes up must come down，I'll be around while you heading towards death town，Always look forward hardly never look back.
So many tears and the snakes on my jack，Now I'm riding in my big fat ride，Your ass is late so look for the line.Nana’s in the house to let you know，What I see is how I feel，So leave me alone.
Repeat ***
Everybody's trippin' on me，Oh Lord, come help me please，I did some bad things in my life，Why can't you rescue me？'Cause you've got all I need，I know I got to pay the price.
Knock on my door，Whom you lookin' for？A dream or reality enemies at the door？Eyes I realize it's fantasize.
I must be high，So let me live before I die，Grabthe bottle the cup and survive，Your life is yours and my life is mine.
No emotions in this world full of lies，Step by step and be versatile，Love peace and crash that's what it's all about，Alone by yourself than you lack there's no doubt about.
I'm always into something making moves to improve，What will you do if you wear in my shoes？Boom, a letter oops another suicide？Meet me for a ride at the boulevard.
Nana's in the house to let you know，What I see is how I feel and damn.
Repeat ***
Everybody's trippin' on me，Oh Lord, come help me please,I did some bad things in my life，Why can't you rescue me？'Cause you've got all I need，I know I got to pay the price.
Repeat ***Repeat ***
That's why I'm lonely lonely lonely，I am so lonely lonely，I'm lonely lonely lonely in my lifeAh~~ah~~ah~~~
