Looking for a song!(English Version)

I'm looking for the English version of two songs I heard in anime,they were both in english. So if someone can suggest a site where I could download mp3 of it in 320kbps it would be much appreciated.

1)Trigun-Sounlife (rem)in the anime its in english but could only find the jap dub of it.
2)Madison's Lullaby the english song that is in Cardcaptors.
