Merging Tracksi Tunes is treating these three tracks as if from two different albums.
Get Info shows they already have consistent album & artist details so overtyping won't help.
When you first install and set up i Tunes, it may automatically search for your digital music files and add them to the i Tunes library. If you allow this, there will be two copies of each of your digital music files on your PC, doubling the amount of memory your files take up.
If i Tunes is already installed, you will have to transfer your music manually. If you don't know where they are, double-click on "My Computer" and search for digital music files. You can decide to leave your digital music files where they are and i Tunes will be able to play them.
To rid your Mac of music, you may want to consider i Tunes Match, which allows you to stream and sync your library through the cloud.
