How do you put a "spacer" track into a playlist?

Is there a way to use iTunes to create a "blank track"?

I don't think so (at least not up to version 7.5 which I use). I did something like that by using an audio editor to make a 1 second silence mp3. Then I made a bunch of copies so each one could have its own id3 tag information.

Not really, unless you use the method mentioned above ^.

However, as long as you are able to make a mental or written note, you can put songs in a playlist in any order you like. So if you add a song 2 months from now to a playlist, you can put it anywhere you like in the playlist, youd just need to remember yourself where you want to put it.

Maybe, in the song before the space you want to save, put a comment in the comment field of the song, and then display comments on that playlist to remind you.

Find the song in the iTunes Store. (If the Store doesn't have the exact song you are thinking of, find one similar enough that will remind you.) Drag it into the playlist. That creates a placeholder.

If you later buy the song from the Store it will automatically replace the placeholder; if you get the song somewhere else, you can replace it manually.

What is the point - you can reorder and drag tunes to what ever order you want in a PL if you sort with the left most number column.

If you need a reminder then add the same track 2 times.
