How to get my music back on my iPhone? - 2

So I just upgraded to iOS7, and because I needed 3gb of space free, I deleted all my music as I thought I'd be able to download it again. I go on iTunes on my phone and try to download it again and it says I've purchased everything, so Icant download it again. Worse thing is, is that none of it is on my laptop as my laptop is broken and i don't know my music just isn't there. Any way I'm able to get my music without using a laptop?

Simple… Just turn on siri and tell her 'bring back my music files which i stored previously on this phone or die b**ch'…
