intergalacticfm on a mobile?

I remember seeing the answer to this somewhere, but had a search and came up with nothing.

My current phone is on its last legs. It keeps turnin itself off randomly and the speaker makes everyone sound like a dalek.

basically, I wanna get a new phone, but I want it to be able to play music streams off the internet.

What kind of phone would I need and what kind of capabilities would it need?

all my old phones havent been 'up-to-date' as you would say and Im not really big on mobile phone technology so I apologise if this should be easily answered.
