Looks like a helluva lotta fun!
Metallica songs are so damn long that looping isn't a big deal to do because making it to the end of a 6-7 minute song is tough. The songs rewind a little bit after draining so that extends each song too. Makes it a little more difficult to replace songs on Metallica by trying to find good songs that are close to the same length as the original track. I don't recommend putting two songs in one slot even though it can be done. You just don't end up hearing much of the 2nd song and if you drain soon after the 2nd song is started the "rewind" will go back towards the end of the first song. Just not a satisfying solution. Looping works best for Metallica if you want a shorter song in a long song slot.
