Can I re-buy something on iTunes?

Asked by kayyyyleigh (404) December 1st, 2009 from iPhone

I bought an album on my iphone, but I also want it on my ipod touch. considering my computer is broken, the only way I can get songs is to get them directly onto my ipod. can I click buy on the album on my ipod as well, without being charged again for music I already have?
thanks(:
