Importing user-created songs from the forum requires that you also find and include (in the BeatBuddy Manager (BBM)) the drum set that the song was made with. For example, Is This Love was made with the NP Standard Bass Hammond kit (from GarryA). Unfortunately, that kit is no longer available from the forum; you can tag GarryA and ask him to make a download link to that kit available again.
Or, you can try downloading, unzipping, importing and activating Phil Flood’s 2082 Hammond with Bass 84+C1 drum set. This song is not a loop, it’s a one-press bass with keys and it should play all the way through once and then stop.
This song requires a double-tap to start playing. Why is that? Because GarryA (as well as some other user-created songs), have the entire song in the Outro which requires the double-tap.
As performed by Bob Marley, the recorded version is 3:56 long—about the same as the song GarryA posted.
