Even better: you can redownload all of those items from your account for free!
You'll need to have had the i Tunes Match subscription, and have matched your files, prior to the crash, but if you did that, just re-install i Tunes, sign in with your Apple ID, and then follow the instructions from using i Tunes Match with i Tunes.
One of the best features of i Cloud is that it retains a record of every single thing you've ever bought or downloaded from the i Tunes Store.

— but it's better than nothing if all of the other options on this list haven't worked for you.
