what are some challenging songs to play on the drums? nothing with double bass because i dont have one.

Define, "challenging".

not very hard, but not very simple/easy

Try "We threw gasoline on the fire and now we have stubs for arms and no eye-brows" By NOFX. No double bass but it's pretty fast.

Not sure if it's double bass but try

Rosetta Stoned by Tool, lots of their stuff has polyrhythms and whatnot.

led zeppelin songs are always good to learn. i was told that once i could play those with a regular pedal i was allowed to move on to a double bass pedal. i play guitar now and to this day cannot use a double bass pedal.

im learning in my time of dying, its fun

play along to the red hot chili peppers

always fun

He said challanging.

I don't really know any single bass songs but mybe some Iron maiden?
