How to use iCloud to add just a few albums to my iPhone?

On my iTunes and iPod touch, I have a massive load of music but I only want a couple of albums on my iPhone so it's not all clogged up, is there a way of putting just a few albums on iCloud then downloading them to my iPhone? I don't really know anything about iCloud.
