Is there music library software for OSX that works like Picasa does to replace iPhoto? I'm kinda new to OS X, but loving it. I have decided to replace iPhoto with Picasa and want a replacement for iTunes that works more like Picasa.

There are just some apps that really get on my nerves. For instance, it really bothered me how iPhoto moved all my photos that I had carefully organized, to some random folder. So finally I decided to switch to Picasa, which has the exact same functionality and doesn't move any of my files.

Recently I'm having same troubles with iTunes: I can't find where the music files I just imported from a CD are, and I just found out that iTunes creates a huge folder where it copies all your music files (this folder, in my case, is over 50 Gb). All of this is really annoying.

Is there any option for iTunes, such as Picasa for iPhoto?

EDIT: I'm basically looking for something to organize and play my music nicely, with a good OS X integration. I don't have a iOS device, so no sync or cloud service is actually needed.
If you like the basic functionality of iTunes, you can just disable its folder management activities in iTunes Preferences by removing the highlighted check marks below:
