Some Rhythm:
RJD2 -- Smoke & Mirrors (Inspiring and mellowing. Helped me unwind rather quickly while under stress and focus on what I'm doing when not under stress.)
RJD2 -- Ghostwriter (Another masterfully crafted song. Good enough rhythm get a pulse of creativity from.)
RJD2 -- The Proxy (Nice background beat.)
DJ Shadow -- Organ DonorSome Anime Tunes:
The Pillows -- Last Dinosaur (These guys rock with the whole soundtrack of FLCL.)
The Pillows -- Funny Bunny (Nice song for a rainy day.)
The Pillows -- Crazy Sunshine (Always seems to give me an emotional powerup. Then again, remembering the episode's climax...)
The Pillows -- I Think I Can (And an awesome song to end the series with.)
Uverworld -- D-Techno Life (One of the better Bleach Openings; held my interest when the next season rolled on...)
High and Mighty Color -- Ichirin No Hana (...But this one was more awesome.)
Origa -- Rise (Freaking awesome intro to Ghost in the Shell: SAC 2nd Gig)
And some more regular music:
Sublime - Santeria (Practically a staple of the local tavern.)
Sublime -- Badfish (Nice tune to mellow out to.)
Ten Foot Pole -- Old Man (Holy crap, the lyrics get more relevant as time passes. Plus, having listened since middle school. I'm the old man now.)
Bad religion -- YouAnd a couple classics:
Cab Calloway -- Minnie The Moocher (Screw it, watch all of Blues Brothers. The entire soundtrack rocks.)
The Blues Brothers - Sweet Home Chicago (The Blues Brothers version in full)
Jimi Hendrix -- All Along The Watchtower (Can't forget ol' Jimi.)
Jimi Hendrix -- Fire (Good enough to be my ringtone for a decent amount of time.)
Jimi Hendrix -- Crosstown TrafficJimi Hendrix/The Beatles (Mashup by ccc) -- She Said Traffic (Wait... I think we crossed wires here...)
The Beatles -- She SaidThe Beatles -- HELP!The Beatles -- Let it BeThe Beatles -- Hey JudeThe Beatles -- All You Need is LoveThe Beatles -- I Am the Walrus (I am here; yes, you are here; yes, you are me and we are all together...)
The Beatles - Strawberry Fields Forever (...Okay, let's face it, The Beatles are made of awesome. But if you want a modern rendition of this awesomeness which is actually a decent film as well, watch "Across the Universe". Speaking of which...)
The Beatles -- Across the UniverseAnd a closer for now, some classic rock:
Aerosmith -- Sweet EmotionThe Sweet -- The Ballroom BlitzHeart -- Crazy On YouQueen -- Bohemian Rhapsody (Is this the real life? Is this just fantasy? Caught in a landslide though it's escape from reality...)
Of course, I can also advise checking out the Trope page of Crowning Music of Awesome, but where's the fun in that?
