iTunes Greatest Hits Collections

iTunes is currently offering some greatest hits collections for $7.99. I have already greatly surpassed by iTunes budget for the month (don't tell my wife...she doesn't read my blog) but a couple of these (my "must have's" would be Miles Davis, John Coltrane, Tears for Fears, Queen and Journey) are a must for any music lover. I may be forced into purchasing them. Don't tell Kim or Dave Ramsey...
