The Accordion Play-Along series features custom accordion arrangements with online audio tracks recorded by a live band. There are two audio tracks for each song, a full performance for listening, plus a separate backing track which lets you be the soloist. The online audio allows users to adjust the recording to any tempo without changing the pitch.

Volume 4, Christmas Songs, features eight songs: Frosty the Snow Man * Have Yourself a Merry Little Christmas * Here Comes Santa Claus * The Most Wonderful Time of the Year * Rudolph the Red-Nosed Reindeer * Santa Claus Is Comin' to Town * Silver Bells * Winter Wonderland
