Tzachas (Greek: Τζαχᾶς), also known as Chaka Bey (Turkish: Çaka Bey) was an 11th-century Seljuk Turkish military commander who ruled an independent state based in Smyrna (present-day Izmir). Originally in Byzantine service, he rebelled and seized Smyrna, much of the Aegean coastlands of Asia Minor and the islands lying off shore in 1088–91. At the peak of his power, he even declared himself Byzantine emperor, and sought to assault Constantinople in conjunction with the Pechenegs. In 1092, a Byzantine naval expedition under John Doukas inflicted a heavy defeat on him and retook Lesbos, while in the next year he was treacherously slain by his son-in-law Kilij Arslan I. Smyrna and the rest of Tzachas' former domain were recovered by the Byzantines a few years later, in c. 1097.
Very little is known about his life, and that mostly from only one source, the Alexiad of the Byzantine princess Anna Komnene, daughter of Emperor Alexios I Komnenos (r. 1081–1118). He is also mentioned in the 13th-century Danishmendname, but it is not a very reliable source due to the semi-legendary nature of its material.
Every time when I'm feeling blue
I look inside me and I remember you
Every time when I'm feeling blue
I remember you
Some words in my mind
Talk about it all time
Again and again
And they just make me cry
Oh baby, come on
Before you give up and go
Could you believe in love?
Bad words and good times
In my mind don't survive
Again and again
And they just make me die
Oh baby, come on
Before you give up and go
Do you believe in love?
Baby, I wanna shake you up
Shake you up, shake you up
Do you wanna take my heart?
Baby, I wanna shake you up
Shake you up, shake you up
Take me up, baby, give up
Baby, I wanna shake you up
Come on, baby, shake you up
All I want is another way
Baby, I wanna shake you up
Oh my baby, shake you up
All I need is another say
Sometimes on my mind
I remember those times
Again and again
And they just tell me lies
Oh baby, come on
Before you give up and go
Could you believe in love?
Bad words and good times
In my mind they revive
Again and again
And they don't say, "Goodbye"
Oh baby, come on
Before you give up and go
Do you believe in love?
Baby, I wanna shake you up
Shake you up, shake you up
Do you wanna take my heart?
Baby, I wanna shake you up
Shake you up, shake you up
Take me up, baby, give up
Every time when I'm feeling blue
I look inside me and I remember you
Every time when I'm feeling blue
I remember you
Baby, I wanna shake you up
Shake you up, shake you up
Do you wanna take my heart?
Baby, I wanna shake you up
Shake you up, shake you up
Take me up, baby, give up
Baby, I wanna shake you up
Come on, baby, shake you up
All I want is another way
Baby, I wanna shake you up
Oh my baby, shake you up
All I need is another day
