Whether or not a song is covered, there was an original artist who originally performed the song. The only issue is that an Artistsongs table will almost be the exact same as the Albumsongsartists table, since most songs aren't covered. So, it may be better not to populate that table by default, and then if two albumsongs with different artists share the same song, then fill the Artistsongs table.
For some reason, I had date in "raw_scrobbles" set as an i32.
Pretty annoying considering I'm probably going to remove the
raw_scrobbles step at some point anyways.
