(help pleae) hiphop or rap + maching band/drums/tubas

So sorry to bother you kind people, but I have run out of any sort of progress on Google searches.

After talking with a friend, I decided to compile a short playlist of 5 or 10 songs that are rap or hip/hop that include marching band elements (aka: fast drum lines, tubas, horns, etc).

Madonna+Timberlake+Timbaland's new song, "4 Minutes" is a good example with the sorta tuba-synth running throughout (especially at the beginning)... but I remember there being 4 or 5 songs like this type maybe 2 or 3 years ago.

One that I have found so far is "Roc-A-Fella Billionaires" featuring Jay-Z...

But I know there were several others. Especially on that I can only remember the tune of (no lyrics, sorry) that had a deep low running tuba (bbuuuuuuuummmmm, da-dat) if that even makes sense.

Thanks for any help.
It's so appreciated.

and oh, if it makes any difference...they were very popular, top-of-the-charts, type of songs. Nothing too obscure.

Fergie - London Bridge has a sort of brass band sound?

Yeah, London Bridge isn't bad, but not exactly what I'm looking for. Maybe a year or two older than that. There were quite a few that had that rat-ta-tat snare sound like marching band drum lines and two for sure that used really heavy deep tubas.

Dang it, this is killing me.

Pan, thanks for the help.

Ok. Just got a call from a friend.

Usher, Caught Up...is one of the ones I was thinking of. Perfect.
Hear the tuba? ba-buuuuuummmm.

But, I know there were a couple more similar to this.
And then a couple more with the real heavy snare drum line.

As always, thanks for any help.

I don't know why as soon as I read the title all I can think of was hmm maybe you'll find something off the Drumline soundtrack..?
