Can you tie two songs together on ITunes/Your IPhone?

I have a feeling this answer is no, but say that I have two songs I bought on ITunes, and I want to be able to shuffle my music, but still have these two songs always play one after the other, is there a way? Or if not, maybe just a way to combine the two songs somehow?

Go on to a free audio editing software, put the tracks together, save and put it on to your phone.
