What does message send failure mean on iPhone? - 1

I sent this person a iMessage and it didn't go through and said "message send failure". I've texted this person before and had no problems but now it's saying this. The person I'm texting also has an iPhone. What does "message send failure" mean? Could it mean that there phone is off?

Cheapest cell phone plan for an individual?

I've shopped around various carriers (atandamp;t, Verizon, t-mobile, sprint) but they all seem to land in the same price range around $80-100 per month if you purchase a cell phone through them. I currently have an iPhone 4 on my mom's plan but am breaking off of her plan since I'm out on my own now. I don't really have a budget I have to stick to at the moment but don't want to put myself into a bind for when I do start budgeting by having an outrageous phone bill. I do however need a new phone because my iphone 4 is falling apart (i've had it since I was 16 and I'm now almost 21), but am wondering if I'm better off purchasing a 5c or 5s Retail Price off of Amazon then just using one of the carriers for my data talk andamp; text instead of being bound to them by purchasing a phone through them. I'd ideally like a plan that'll cost around $50/month but I'm not sure if that's possible since I do need a new phone as well. I feel like I'm being price gouged here lol.

ITunes: How do I get music purchased on my phone onto my computer library?

Here's my problem: I purchased a few songs from iTunes ON MY PHONE, therefore, that music is not on my computer iTunes library - just my phone. I want all of the music that is on my phone to be on my computer, BUT, I DON'T want all of the music that is on my computer library to be on my phone library. (The computer is a 2010 Macbook, and my phone is an iPhone 5).

I want that music that's on my phone to be on my computer BECAUSE I want to use that music from my phone for iMovie - which of course if you've used iMovie you know you can only select music from your iTunes Library on your computer, and those certain songs aren't on my computer, they're just on my phone, etc you get the jist.

SO can someone please tell me JUST how to get all of the music that's on my phone onto my computer iTunes library? AGAIN - I wanna make this as clear as possible - I DO NOT want music from my computer to go onto my phone (I DON'T want it vise versa). For example, I have every single Beatles song on my computer, but I don't want all of those beatles songs on my phone because of the enormous space it takes up and I don't listen to them on my phone. Hopefully you get what I mean.
