iTunes is pissing me off

I love iTunes.  The minute I got an IPOD, I started using it.  It is extremely easy to use and I quickly gave up winamp.  Now, I am pissed.  I recently wiped my laptop.  I do this at least 4 times a year(probably more like 10).  I put a lot of experimental software on it and it gets bogged down.  This is pretty common(for me).  A couple years a go I got smart and partitioned my hard drive and put my documents folder with all my other user created  data on the partition.  So I reinstalled everything including iTunes and pointed everything to the My Documents folder.  When I reinstalled iTunes it wrote over my old iTunes library database with a brand new one.  I spend a lot of time setting up that library .  I backed up my data nightly, swhich saved me, but when you reinstall iTunes, it should search your hard drive for an iTunes library and ask you if you want to use that instead of overwriting it.  I have no ideal why this would be of interest to anyone but me.
