You should expand your requirement to iCloud and Dropbox for following reasons.

1. iCloud is sandboxed to only certain apps. In other words, any notes an app X creates cannot be read and modified by app Y. Dropbox allows any apps that supports Dropbox to access your notes. You may like app X now but you may want app Y later.

2. iCloud syncing can be useful if you have multiple iOS devices, for things like settings and miscellaneous data (e.g., scratchpad).

I have tried over a dozen note taking apps that syncs over the cloud. The app that I keep going back to is Elements (http://www.secondgearsoftware.com/elements/). It has very clean yet functional UI and frigging fast.

I do have few wish list items though: (1) tagging and/or support for moving notes to different folder, (2) hide certain Dropbox folders (I linked to the root folder), (3) default font setting (Museo Sans is very pleasant but may not be for everyone), and (4) Markdown keyboard (it fully supports Markdown but I don't remember all the syntax).

iTunes will actually let you use multiple libraries if you want, and then can switch between them on launch. So if disk space (and just keeping the files where they were wasn't an issue), you could use a second library.

If you launch iTunes while holding down the Option key on your keyboard, you will get this dialog.

You could choose 'Create Library' here, and make a second library.

Unfortunately, the storage location of your music is a iTunes general setting versus per library. But, there is the options in Preferences -> Advanced to not copy files into the iTunes Media folder. Changing this though would affect your main library too though.
