I have two musical tracks that I follow.
One wants lyrical cleverness, catchy melody, upbeat playfulness... sometimes a sense of nostalgia. This side goes for music like They Might Be Giants, Sparks, The Beatles, Flaming Lips, The Unicorns, Weird Al... so basically clever pop music
The other wants, complex rhythms, deep textures, new sounds, emotional melody... all wrapped up in a compelling, attention grabbing musical package. This side likes Don Caballero, Squarepusher, Four Tet, old school video game music (SNES, NES) Pink Floyd, Battles, Drums & Tuba, Yes, Jethro Tull...this side likes prog rock, jazz fusion, interesting electronic music, and anything that's experimental yet still good.
My go to music, all time favorites are They Might Be Giants... and probably Battles... even though they are pretty recent. Something about their music is the pinnacle of that complex, interesting, and yet still fun music that I can't get enough of.
