Compressing music files

Hi
I have a Desire....(sounds kinda wrong!)
I'm using a 16gb sd card. But its completely full. I copied and pasted my iTunes libary to it. I have 3500 tracks which is about 15gb.
Im very slow with computers etc and was wondering if there was anyway to compress my music to free up some space. I cant even take photos with the phone now because its saying I have no storage.

Bit gutted really I asked on another thread how much and where can i get a 32gb but they said there not available yet.

Please help

 

Honestly...........Lmao. Cant you stand it. Does it rile you up and get under your skin?

Calm down, have a cup of tea. Its only a computer. Im sure the artist wont lose any sleep and nether should you.

Now does anyone else have any tips or hints. Im actually quite fond of my music collection and dont really want to delete any more tracks. Im sure if I compress to a really low bit rate then the quality is bound to suffer. I was hoping that there was maybe a program that squeezes out the blank spaces etc or something down that route.

Advice please

 

Thanks, sounds good. Even if it doesnt work I can reformat the disk and copy my original music back on it.

Ill give it a whirl
