^^have you used the latest one?It has pretty cool GUI.The main feature of media monkey in the no. of tools it packs and automatic tagging of songs in metadata.
of course it your collection consists of mainly untagged or improperly tagged songs then its very difficult to browse.
Each and every file in my Collection is Tagged(+Album Art) , but still the Library Browsing of MediaMonkey has a lot of hiccups and leaves a lot to be desired .
Like for example when you wanna browse by album , you double-click on album-name , then rather than displaying the tracks in the album , it just starts playnig the whole album , and you actually have to change to track-view and find the song all over again to view tracks in that album.
Compare this to WMP 11 , it shows album art-covers , when you click on album , it shows tracks .
Similarly , in Artist view , in WMP 11 you click on artist it shows all albums by that artist along with tracks .
In mediamonkey , in artist view , it just sorts-by artist rather than have a custom-view for it .
Overall feel of Mediamonkey is very clinky .
