Just got songbird today its v1.4.3 now have not synced it to the N900 not sure if I want too

For me drag & drop works just fine since the N900 is a mass storage device, but since the N900 supports all the meta data and cover art it has sent me on a quest to embed the proper cover art and update all my tags on my music.

I just used folders in windows, would find the folder for the music I want and tell it to play in winamp. This kind of use is almost just like mass storage so it was natural to me, but now that I have about 1/3 of my stuff with cover art and updated tags it feels like its "going to waist" just using winamp and browsing to a folder for my music.

So saw how songbird works with the N900 and noticed how it filters by meta data and shows cover art, and thats the reason I am using it right now. Still feels a bit akward and I have a lot of japanese music that there is no way I can tag but meh.

So that side story aside, what benefits do I get for using a syncing program like songbird instead of just drag & drop the music I want?

I have more than 32GB of music so it cant all fit in the N900 so it cant just "sync" my whole music collection to the device.
