I accidentally deleted some music that I bought from iTunes on my iPhone 4s?

I was messing around and I accidentally slid my finger over it at deleted the songs. I went back on to iTunes and it says that it is "purchased" but I can't download it again?

Step 1.turn off
Step 2.turn back on

Yes you can. All you need is the iTunes password for the account that pops up and you can download any previous purchases from iTunes.
