I have recently been listening to Guided by Voices. I downloaded a random few of their albums after watching some videos of them that were related to Pavement videos on YouTube.
They are enjoyable to listen to. Some of their songs are kinda crap, some of their songs are really good and most of their songs are very okay, but are nice to have on in the background when you're doing other things because they make you feel like you're a nonchalant Generation-Xer in Clerks or something.
They make that kind of messy, 90s lo-fi type indie rock that makes you feel okay about being disgustingly lazy as it feels like (and sounds like) they're probably just as disgustingly lazy as you are. However, unlike you, they have the capacity to sound really rocking, in a similar way to songs like Summer Babe by Pavement and Sacred Attention by Sebadoh.
Here are some of my favorite songs that I have heard so far by them. They're probably not their best songs though, as I haven't listened to them nearly as much as I should have, especially considering that I'm writing a blog about them.
Oh also, I forgot to say that their songs are all really short, which means they get extra brownie points.
