Pretty much on straight repeat, Raekwon's "Only Built 4 Cuban Linx...", for about two weeks now, interspersed with the occasional reort to DangerDoom's "The Mouse and the Mask" and Lupe Fiasco's "The Cool".

Here's some Raekwon, because really, doesn't it always make a day better?

Yes it does. I used to listen to that all the time about 10 years ago. Ice Cream is the first song that comes to mind.

Yuppie Flu, Food for Ants

Some weird latin stuff they're playing in Starbucks.

I'm usually more of a hardish rock fan but the Gorillaz have really hooked me.

Very few hip hop fans here, apparently. Well, this ought to make you one...

@Ebay:

If you like Butthole Surfers, you gotta go way, way back. Live album called PCPPEP. Great album. Small setting. The crowd at points is yelling at the band to "shut the f*** up". BBQ Pope is awesome from this set, and possibly the best song ever recorded.

Too much to list. Two Weeks used to be my aural cocaine. If you're fan of Grizzly Bear, I can probably give you some recommendations. A pretty similar band is Local Natives, here's a song:

And here's one by Edward Sharpe and the Magnetic Zeroes, for good measure:

Just to appease Bob, though he's probably got these down,

Sheeit, Chris, I almost linked to that exact Madvillain song when I opted to put up some Black Star instead. I am a huge MF Doom fan, and frankly, there's so much Madlib out there that anyone up to and including my friends 99 year old grandma can find something they'll dig.

Ebay, not exactly what you were asking for, but have you heard of pandora.com?

You give it an artist or particular song to "seed" a "radio station" and it plays similar songs. You can then thumbs up and down various songs to "tune" the station to better match what you enjoy. I've found a lot of music on pandora that I'd never heard before.

Best dubstep I've heard in a while, and they're from Toronto!

I'm listening to the sound of the office at uni

atm, i am listening to Fleetwood Mac... lol

Barber's Adagio right now. Mozart's Serenade for Winds, K. 361 a little while ago. Probably Gershwin's Rhapsody in Blue next, unless I change my wind and go for Copland's Appalachian Spring.
