Slower or faster loading playlists depends on wma/mp3?

I’ve noticed something on my 8 GB (latest FW) Clip:

Playlists of WMA-Songs (+/- 100 Songs) took LONGER to load than much longer playlists of 200+ Songs, which contains about 90% MP3s and only a few WMAs.

At least I think that’s the problem that causes the shorter playlists to load longer.

 

Though, doesn’t seem logical to me.

 

My question is: Is that a common problem and why does it appear?

 

Thanks,
