Trinity Hymnal Baptist Edition. I currently use some of the standard Trinity hymnals for family worship, and merely skip the paedobaptist songs. :)
The Trinity features some of the most excellent of hymns of the faith, and I appreciate that they offer a "Baptist" flavor of this hymnal. The songs, with midi, can be found listed here. Alas, no sheet notation, but if you hear it a couple times you can pretty much pick it up in order to sing it without instruments.
