Great choice - really good album. Enjoy the Replacements a lot and own four of their albums, but they are interestingly a group I listen to in spurts often separated by a year (last fm reminds me I last played Tim 2 yrs ago) - perhaps because I didn't get into them until my 20s rather than when I was in college and groups often stick a little more.
Tim definitely finds the Mats more production-savvy and a bit mellower that on Let It Be, but the music is great. Wonderful listen
Interestingly, they are among the artists banned for life on SNL after appearing on the show in 1986 to do songs from this album - apparently rude and bawdy behavior. I bet if they did this during the Belushi years, it would have been OK

Have no idea why the album is named
Tim and have never researched why - there are no Tim's in the band
Off one website, reportedly a Westerberg quote from Jim Walsh's Replacements book
