He's a good bass player and thus it's nice to see him back in Dinosaur Jr again, but I don't really like Barlow as a songwriter.
Lose and Poledo are easily the worst songs from You're Living all over Me, they're pretty terrible songs that hurt an otherwise great album.
Oddly enough Punchup at a Wedding is the one song from the album I'm not too crazy about.
I don't think it's any less consistant than the other post PH Radiohead albums, personally.
I thought Green Mind was decent but I agree that they started going downhill around that point.
I dunno if that's really because of Barlow's departure or just because Mascis started running out of material, I think it's the latter. There's nothing about Sebadoh that convinces me that Barlow is a particularly talented songwriter, I just don't get his appeal.
