There was a thread (Thread 72072) on it before, but all the links have expired. I'm looking for the MP3s, including the instrumentals. Thank you in advance if you're able to upload it!

Track names:
01. Kimi ga Iru Kara
02. Eternal Love
03. Christmas Again
04. Kimi ga Iru Kara (Instrumental)
05. Eternal Love (Instrumental)
06. Christmas Again (Instrumental)

Hi! I posted it in the download links forum so that others can find it easily if they're interested. Enjoy!
