Help for some songs in CSS

[Aaaaflasd]

Well for CSS whenever I convert it, I follow the instructions, but then it turns out all bad and stuff. When I compare it to my regular non-wav file I just wanna cry.

I am looking for the modded versions of these songs that can be used in CSS and have Great quality, also help is appreciated. I followed every instruction but I don't know why it doesn't work. Anyways here are the songs I would like.

Switchfoot - Oh! Gravity
Beyonce - Halo
Britney Spears - Circus
Avenged Sevenfold - Seize the Day
Bullets for my Valentine - Tears Don't Fall
Chasen - On and On
Kings of Leon - Use Somebody
Red - Never Be the Same
Mint Royale - Singing in the Rain
Needtobreath - Streets of Gold
Nelly Furtado - I'm like a Bird
Owl City - Fireflies
TobyMac - Burn for You

Thank you help is appreciated

Just to remind everyone, the audio converter can be found for download on the downloads page, so there's no excuse for conversion problems.
