"What is psychedelic music???"

I'm listening to Verve's A Storm In Heaven right now, and 'Beautiful Mind' came on. I would call this particular track (indeed, most of the album) 'psychedelic', because its rhythm section is so god damn subtle, but on top of it are just the most heavily-reverbed and effected vocals and guitar lines. Having said that, I'd say 'Make It 'Til Monday' is probably the most 'psychedelic' moment of the album.
