How to find my music on itunes?

I just logged into itunes on a new computer and can't figure out how to see all my music. I also got different iphone, so the music is not on the phone. Can anyone help me figure out how to get all my music?

Added (1). This is the first time I'm using itunes on this laptop, I plugged in the new phone to the computer and it opened up itunes. All my music was on my old laptop. Does that mean that I have lost all the music since I can't import it from files?

How to download free music on my iPhone?

Please Help ME!
So fed up of all my friends laughing at me about spending a fortune on a couple of hundred songs when they're simply downloading thousands of songs for free!

Is it possible to just download free music straight onto my phone?

Or do I need to do it through a computer? Because unfortunately all my music is only on my iPhone as my laptop has broken down…

If it is the computer option, can you please name a couple of good sites? Ones that are simple enough but with a lot of songs.

How to activate new SIM card in iPhone 3gs?

A friend of mine has just given me her old iPhone 3gs. I reset all the settings and data and inserted my SIM card from my previous phone. However nothing happens when I do this. I can't make calls and if I try to call the number it doesn't work. Do I need to activate it or something? The phone seems to register that there's a sim card in there because when its not in there it comes up saying there's no sim card.

My Iphone 4s won't keep its charge?

Last night I had my phone plugged in all night long, then this morning it only held its charge for about 30 minutes. It only works if it is plugged in and never goes higher than 1% power level. I've double clicked the little round button twice and canceled all the open applications and it's been plugged in for a couple hours now.

I really don't want to have to go in to the Apple store, does anyone have any suggestions?

Should I buy an iPhone over an Android-Smartphone?

What really attracts me to android devices is the HD large screen, features such as DLNA (for wirelessly streaming media from the phone to a compatible TV or computer -like in HTC devices-) and lastly, more storage as per price.

please share.
