Will adding music to my iPhone slow it down?

I'm getting an iPhone 5 this friday and i want to know if adding music to it will somehow slow it down? I currently have 253 songs on my itunes and i'm getting a 16GB iPhone. Will it affect the way the iPhone works? I have an ipod touch as well. The newest kind. I just wanna know if i should add music or just carry around my phone AND my ipod.

No it won't…

No it should not slow it down as long as you have 1 GB free it will be fine after exceeding that it will be a bit slow nothing to cry about though

Not as long as you don't add any Taylor Swift or Justin Bieber music.

No, add music to iPhone will not slow it down.
