I just downloaded the Limewire and not sure if its all that!!

I'm knew at this and thought well it will take a little time to learn but after reading some of this forum I'm not sure if I want to continue with it! It's so slow and not easy to learn. I paid money for it too.

Should I stay with it?

I want to be able to listen to music without interruption!

I want to learn how to download the music onto a CD and be able to get anywhere between 10 to 15 songs on a CD.

I bought a couple of songs throught the internet legally and I was only able to get 1 1/2 songs on the CD and I don't know why it took so much space?
I have windows xp and windows media 9 player that I used and downloaded on a TDK 80 MIN 700MB CD-R...

CAN ANYONE HELP AND LET ME KNOW WHAT i DID WRONG?

THANKS
