If you're into the whole noise pop sort of thing check out Wavves, Vivian Girls, No Age. if you want just acoustic shit try mountain goats, devendra banhart, elliott smith (though these are all pretty obvious).

for spacemen 3-like bands the best one i can think of and absolutely love is Loop. extremely underrated but if you can try to find the album 'the world in your eyes' its v. good. the telescopes are in a pretty similar vein. a place to bury strangers are really good too, they just released a new album though i prefer the older one. galaxie 500, the fall, can and faust are also all good older bands worth checking out for sure. 

if you want newer stuff try checking out the Horrors (both the first and latest albums), also just started listening to sparklehorse, he's really good too and usually does collabs with artists like iggy pop and vic chesnutt. i only have the album 'dark night of the soul' right now but you should check it out and see if you like it

XD

i don't really want to make a new topic but i feel like this is more of a casual place ot talk about music so it can be that now okay.

have you guys heard of pissed jeans? i just got their 2009 album king of jeans and its excellent. a really sludgy heavy sound (though not as noisy as their previous record, it seems). really reminds me of jesus lizard, butthole surfers and the melvins
