Multitasking is all about running several processes at the same time. The N900, via the Linux kernel, does this "beautifully".
But, this doesn't mean that there are unlimited resources for the running processes. And since it's very easy to hear when music stutters, this becomes very obvious when playing music and doing something else at the same time.
It's not as easy to spot that the scrolling done in the browser "stutters" too while the phone is busy with many tasks.
So, this sounds like you need to adjust your expectations a bit. Either you make more resources available (overclocking is one way) or you adjust to how you can use the resources that are left while multitasking.
Being a bit more technical, sound is troublesome on the N900 because of, in my opinion, two things: using PulseAudio and not using the proper scheduling algorithm in the kernel. PulseAudio uses lots of time in the CPU to do all the things it can do (which brings some nice features) and this punishes all other processes.

Hey guys,
I'm not here for any rant or anything, so this is what happens yesterday,
My iPod touch breaks, so I say, Hey I got the N900, lets use that for music now !
I am multitasking, Browsing few pages, some IM's coming and going, and music playing on shuffle and what do I hear every time I try to browse or send an IM or read an IM - Music stuttering !
now we've all heard that the phone multitasks beautifully, why does it fail to play music properly while using other features of the phone!
does it need anything tweaked?
any help appreciated !
Cheers
Jackie
PS: I run stock clock speeds !
Anyway more like you don't know how to use your device.

I understand that the N900 has limited resources, but something like playing music smoothly is one simple expectation, I remember my 5800 doing this very easily ! I'm not sure about the whole overclocking thing due to battery issues !
Nokia must do something to fix this, either switch from Pulse Audio to something else, or try to optify the whole media player !

But, it will stutter once if the screen is dimmed or woken up. This is due to the change in CPU frequency.

for example subtitle or extra codec. Those are known to cause problems, also the sms music title style app also causing problem with the media stuttering. Mine is stock and i'm not having this problem since after i uninstalled those
Beside this is Maemo 5, it is not Symbian S60 OS. Symbian has different OS and use limited multitasking but N900 has full multitasking and runs like a PC. Even a PC struggle to play music sometimes. I must say the browser in PR1.2 is slightly buggy riht now and it consume a lot of resource. Hope it get fixed soon.

@Joorin,
Mine didn't stuttered at all, when the screen dimmed and unlocking or locking, never stutterred on me. I'm opened many apps and watching flash video still not stuttering
i'm currently opened youtube, facebook, maemo.org, sms windows, music playing, phone app, and sygic and more. Total of more than 9 apps opened without stuting

Editing /etc/init.d/rcS Line 265 to
echo 1 > /proc/sys/vm/page-cluster
helped quite a bit to smooth out multitasking
