Hi I have a Samsung j600 and would like a memory card so I can store more music on there, was looking online but was confused with all the types of memory cards . I don't know which one I need to get. Anyone else know?

Here's one:
Samsung J600 Memory Card (Micro SD) & Accessories - From £4.99 (http://www.mymemory.co.uk/compatible-memory/Mobile_Phones/Samsung/Samsung+J600_Memory_Cards)
Also Google"Samsung j600 memory card", and you will see something like this:

Thank you . Had tried to Google it but there seemed to be so many different types for different things and didn't want to get more than I needed. Will check out the link you sent

What you need is to look at the slot on yuour phone or the phone manual. That will tell you that it uses a MicroSD card.
