DOWNLOADING ONTO IPHONE PREVIOUSLY DOWNLOADED MUSIC.

Question

Hi,
I have downloaded 2 albums onto my iphone over the last couple of weeks.
When i have connected my phone to itunes and synced the music these albums have disappeared from my phone but remain on my computer in itunes music and library. They are also under the "on this phone" icon but when i click on them to play the songs an exclamation mark in a circle appears at the left hand side.
I have tried going onto itunes from my phone to redownload the music from icloud, however when i do this all it says where the icloud icon normally is, is "purchased" and i can't find anyway of redownloaded the music.
I have also tried to redownload them from the itunes store on my computer but this hasnt worked either.
This is very very very frustrating!!
Apart from throwing both my computer and my iphone out of the window i have no idea what else i can do..
Suggestions and help welcome,
Thanks
Charlotte.

Re: How to sync iPhone to (new) computer and keep everything on the phone saved?

If you haven't synced you phone with iTunes before the first thing iTunes will do is delete all iTunes media (apps, music, podcasts, etc.) from the phone, then replace it with the media in the iTunes library you are syncing with.  Establishing syncing for the first time without losing your data has to be done carefully.  This guide will give you the process for doing so: https://discussions.apple.com/docs/DOC-3141.  There is a related guide here as well: https://discussions.apple.com/docs/DOC-3991.  However, as covered in these guides, only music purchased from iTunes can be transferred from your phone to your iTunes library.  Transferring music from other sources from your phone requires 3rd party software such as Touch Copy.
Other options:
If all your music is purchased from iTunes, it can be download directly to your phone for free without syncing (see http://support.apple.com/kb/HT2519).  Another option to get your music without syncing is to subscribe to iTunes Match (seehttp://www.apple.com/itunes/itunes-match/).  This will scan your iTunes library, match songs already in the iTunes store and upload any songs in your library not in the iTunes store, then make your entire music library (up to 25,000 songs) available to download from iCloud directly to your phone.  (With iOS 6 due out next week on the 19th, iTunes Match songs can also be streamed to your phone without downloading and taking up space on your phone.)
