So I've installed leopard (erase + install) which is great, apart from a few old apps not working (Photoshop and Fireworks). BUT now when i open iTunes it wants me to reauthorize my purchased music on my "new computer" - WTF ? is there any way around this ??? some of my songs are on their 4th re authorization (migrated from 10.3--> 10.4 --> 10.5 and from iBook to MBP).
