Josh “TwiTerror” Whelchel has just released The Spirit Engine 2 – Selections for free (as torrent or direct download). “Selections” contains 22 songs from the massive 101 song soundtrack of TSE2 (which is available for $16). You can read a highly favorable review of the latter on RPGFan.
There’s also this great live recording of a 28-track TSE2 arrangement, for those interested. Thanks, Josh!
