Transferring Music from my Chromebook to my iPhone?

I have an Acer Chromebook 13 and an iPhone 5s. Is there any way to transfer the music I have on my Chromebook to my phone? I have looked it up and they all say it is impossible but most of those answers are outdated.

Is there any updated way to transfer this music? Thanks

My iPhone charging port is not working?

I dropped my iPhone 5 in water the other day. I immediately put it in a bag of rice to dry it out. This worked, and the phone was working great. However, when I tried to plug it in, I noticed a full piece of rice that was lodged down in the charging port. I was able to get it out with a toothpick, but the port doesn't work very well even though it appears to be empty. The phone will charge, but it cuts in and out almost constantly, which is very frustrating. Any suggestions on how to fix this.

Should i buy iphone 4 battery replacement?

Should i buy iphone 4 battery replacement?

Added (1). Yesterday, it turn off at 45%, i try to get it to turn back on, today i fix it.
it has around 1900 charging cyles. I read online, that Apple wants/requires you to change battery every 400 cycles. The capacity says it has 600/1420 MAH. About 40%. My iphone would actually shutdown at 20%.

People say the battery replacements are old stocks from their leftover warehouses. I bought a new battery once 5 years ago for my 2002 ipod. And I charged under 50 cycles before battery replacement died.

IPhone white screen of death?

I was in the middle of using an old version of redsn0w to unlock my old iPhone 2g running iOS 3.1.3 when it froze (on the phone) in the middle of the unlock process… Me in my infinite wisdom said ok I'll just reboot it and start over… After a few minutes of chilling on the apple logo I realized something was wrong and quickly put it into DFU mode and plugged it into iTunes to restore it. All was well and iTunes recognized the phone and was ready to restore it until the "white screen of death" appeared as iTunes was "preparing iPhone for restore"… I've tried everything I can think of but nothing works, I can't restore the phone in iTunes and it won't boot on its own. (trying to tethered boot or restore in a new version of redsn0w doesn't work either because the new version of redsn0w doesn't recognize that the iPhone is in DFU mode)
