Itunes music not syncing to my iphone?

I have an iPhone 4. I clicked on music and had it sync entire music library, said it did but was not on phone. So I had it sync selected music paylist ect, had everything check, still did not sync to the phone. When I clicked on this phone in iTunes when the phone was connected, it showed all of my music but it wasn't on the phone. The phone is updated to iOS7 and with the newest update of iTunes. Is there a certain reason why this is happening? My sons iPhone synced perfectly fine when he had this laptop.

IPhone 5s plans for StraightTalk, T-Mobile, and Virgin Mobile?

I'm going to get an unlocked iPhone 5s. However, my parents will not pay for the at&t, sprint and verizon plans. They said that they would do the straight talk, virgin mobile, or T-mobile plans because it is cheaper. I was wondering when the plans would come out for the 5s, and about how much they would be (compare it with the iPhone 4 when it came out). I really want to get this phone fast and start using it.

Should I get a MacBook Air or an iPhone 5S/5C?

I got enough money to buy an iPhone for my birthday, but my mothers says that if I save my money until Christmas, I can get a MacBook Air.
My phone is an old samsung galaxy ace, and it has all sorts of problems. It has very limited space and a very short battery life, and is super slow.
My family's PC is slow, and is running out of space. I need that space for documents, and to be able to synch my iPad with iTunes.
This is a really tough decision, please help!

What does the iCloud download button mean on iTunes?

I just bought the Hp Envy laptop and I want to transfer everything from my iPhone onto my laptop. I already got my pictures on there. Anyway, I got my music to show up in my iTunes library but it has the cloud with the arrow facing down between the song title and artist name. I was just wondering that once I hit the iCloud download button, am I officially putting the song onto my laptop? I'm just not sure if hitting the download button will charge my account as if I'm re buying the songs. Also, my playlists that I've made on my phone won't show up in my iTunes library either. I'm sorry if this isn't clear enough, this is my best description of the dilemma I'm currently in.
