this block of code isn't the clearest. maybe have this instead:

    if(albumLines > artistLines) {
        bottomLines = albumLines;
    } else {
        bottomLines = artistLines;
    }

or 

    if(artistLines >= albumLines) {
        bottomLines = artistLines;
    } else {
        bottomLines = albumLines;
    }

if you want to make it clear that you prefer artistLines over albumLines
