User blog:Kana "Saki Kuro" Clark/This is REALLY urgent

I have a REALLY big problem:

I spend ALL day downloading music from not just iTunes, but also other sites liek myfreemp3. I also download movies from other sites like YouTube. And I sync songs from a CD / DVD player. But today, I made a HUGE mistake. I don't know what happend, but aside from the ones I downloaded on iTunes,

'ALL MY MUSIC AND MOVIES I DOWNLOADED AND SYNCED FROM OTHER SITES ARE GONE FROM MY LIBRARY!!!! ESPECIALLY ALL OF MY PLAYLISTS!!!!!!!!!!'

This is a BIG problem! Now, I have to re-download them. But I don't wanna do that because it will take, like, THE WHOLE SUMMER to do that. I need another way to get them back. SO I have a question (and I need to say it in all caps because this is a huge emergency):

'HOW CAN I GET MY LOST SONGS BACK FROM MY LIBRARY? RE-DOWNLOAD THEM, OR GET A NEW VERSION OF iTUNES? I NEED ANSWERS RIGHT NOW!!!!'

Sorry, sorry. I got a little cranky there. So please, help me out.

(P.S. I still have my stuff on my iPod, thankfully. But I need to download more stuff like VALSHE's upcoming mini album, Jitsuroku Kumonoito. But still, thank goodness I still have my songs, movies, and playlist)
