I have a thing for gamelan music... but oftentimes, the traditional stuff can get a bit busy and frenetic, ruining the mood. Fortunately, there is Jalan Jalan... music by a Japanese electronic / world music composer who bases whole albums around gamelan.
Definitely an underutilized instrument, especially with Western popular music. Peter Murphy would go great with gamelan, as would Bjork, Bowie, Sigur Ros, etc.
Out of curiosity, can anyone remember any examples of gamelan in popular music?
