I think 5 is great, been using it for the whole day and havn't hit any really big bugs, now 5 alpha is a different story, it has bugs up the ying-yang.... Now if you want, upgrade to the unreleased version of winamp 2.95
here
With 5, they are keeping the stability and speed of 2 and implementing all the cool stuff of 3. Very smart for them... It will be interesting to see how this Winamp Pro thing works out. Will people be willing to pay for more advanced features? I might consider it... even if there is a crack that comes out. Support for a product i have liked since i first saw it many many years back.
