Thanks Chanakya for asking.

Ninanoki coming later but I can help with Sinzia.
More info about the Sinzia song, including lyrics is here

This is a good resource for learning Swahili too and for translations
Kamusi Swahili project

Ndani ya nyumba - in the house
Tafuta mpenzi lako - find ur love
Mshike kwa mikono - grab her hand
Ha, mwangalie ndani ya macho - look her in the eyes

Mpeleke kando - side by side
Namwambie(3x) - and tell her

Vile inakushika kwa ma - the way they hold u tight (maybe at the hips)
Kwa kweli manzi umebarikiwa - for real girl, your blessed
Ndio maana tunaimba halleluia - that's why we sing halleluah

Kila siku nakufikiria - Everyday I think of you
Ndio maana nasinzia - that's why I daydream

Nasinzia nikikuwaza (oh oh) - I think of you as I daydream
Miaka rudi miaka nenda (oh oh) - years come and years go

Kilasiku ya calender (oh oh) - everyday of the calender

Chochote utafanya nitafuata – whatever you will do, I will follow
Nitachora nane, ukichora saba – I will draw four, if u draw seven

Nawakijaribu kutu-lay us under– and if they try to lay us under
Mungu mmoja nitawapiga ngeta - I will beat them
Anakama ungekuwa ngoma - if u were a drum
Ningependa kukuwa amplifier - I will like to become the amplifier

Mpaka hata matuta zitachina - If this marks the end then I will delay

Hope you found it useful. Our visitors from East Africa and other Swahili speakers can help us correct the translations.

Oh, and check Kasahorow for more African language dictionaries.

Ehh nyinyi Mabeste - Hey you my friends
twende tukatike - Let's go and dance

Sisi wa Nairobi - We Nairobians/(We of Nairobi)
Tunapenda happy - We like to party

Mumefurai wacha kujidai - You are happy , stop pretending

Si tukatike - Let us Dance

Huyu jikidi, ako na bidii - This dude works hard/is working hard
Anadance kuku, huku na huku - He's dancing 'kuku'(a style of dancing) here and there
Na huyu jamaa, huyu yu shujaa - And this guy is brave (or is a hero)
Anajua kukata, bila kuhata - He knows how to dance without missing

Ogopa DJs wachaku delay - Ogopa Djs stop delaying
Sisi tumefika sasa tutawika - We have arrived, now we will shout(literary translation is crow like a cock)

Oh ameniokowa - Oh he has saved me

Mazee tumebeba, mazee tunaroga, tumefanikiwa – Man, we've carried, we've rapped and we are lucky

Kai muthai raigwa wega -

Mokiina kai mutha raigwa wega wega -
Mokiina mokiina -

Wacha kujifanya una hanyahanya - Stop pretending you are dicing

Parts left out are in Kikuyu, translations coming later
