Is it bad to put music in to an Iphone 4S?

I know this is a stupid question, but I'm jut curious since the iphone is a lot like the ipod touch. I'm going to get an Iphone 4S soon and I'm wondering if it would be a good idea to put music in to it. Is it going to be like any other phone that will slow down if i put music in it?

It'll just waste your storage capacity

I have an Iphone 4s and have like 100 songs on it and it still is really fast. What is the point of getting an Iphone if you don't have music on it anyways. Even if it does slow your phone down it would be such a tiny difference you wouldn't even realize it. Put music on your phone, I think you will like everything being on one device instead of some stuff being on an Ipod and some stuff being on your phone.

Iphones never slow down
