x3 on iTunes. To me it works like a dream. But I've come across some friends who have lots of issues with the Artist sorting, album art, etc. However I realised that those that have problems don't necessarily procure their media through the standard guidelines (buying off iTunes, ripping off CD's using iTunes, etc.). This is only one example - i.e. there's probably further investigation and further understanding needed as to why there are iTunes advocates and non-iTunes believers.
