i really like that list and id say mine is rather similar,
cruisin: MGMT, The Flaming Lips, DJ Shadow, RJD2, Grateful Dead, Hendrix, Allman Brothers Band
Pow: SLightly Stoopid, The Expendables, U.N.K.L.E., trippy music is cool too like pink floyd or jefferson airplane
Mellow park: marley(s), atmosphere, goofy ass wayne tracks, sizzla, capleton, reggae in general, and southern style screwed and chopped songs
HArdcore Park: last year all about hardcore rap like tupac, biggie, Jeezy, some wayne, Eminem, and other shit that goes hard. This year im thinking about listening to music that puts me in a good mood and makes me relax when im trying to get the trick I want cause i tend to stress and get pissed for no reason.
anyway thats basically it and I hate to copy a lot of bands/groups/artists but thats really what i listen to when i ski
