If you already own the first of Ratt’s greatest hits “8191″, there is not much difference on this new release. 5 songs out of the 20 are different. The 5 being tracks 1,7,18,19, & 20. One thing to take note of, the above song track listing is correct, EXCEPT for the last track. It is not ‘No One Can Stop Us Now’, it is an MTV Unplugged version of ‘Way Cool Jr’. The CD is still a good one to buy, if you don’t own a greatest hits from Ratt already.
