Lyrics on iPhone 5S won't change?

I just got a new phone, it's the 5S. I'm testing out the lyrics sine on my old iPhone (4), I messed something up that made it so that I couldn't change lyrics when I messed up. Well I tried putting a song on my new phone, and then changing the lyrics to see if it would work, but it didn't -- when I change the lyrics on iTunes, the song's lyrics on my phone won't change, they stay the same as they were before.

When did you make the changes? On my iPod touch it sometimes takes a dww house or even days before it recognizes changes I've made in iTunes.
