Code:

        <control type="image" id="2000456">
            <posx>645</posx>
            <posy>-64</posy>
            <width>230</width>
            <height>89</height>
            <texture>$INFO[Player.FolderPath,,../logo.png]</texture>
            
        </control>
        <control type="label">
            <posx>515</posx>
            <posy>-15</posy>
            <width>490</width>
            <height>25</height>
            <align>center</align>
            <font>DejaVuSans_Bold_32</font>
            <textcolor>mainblue</textcolor>
            <label>[b]$INFO[MusicPlayer.Artist][/b]</label>
            <visible>IsEmpty(Control.GetLabel(2000456))</visible>
        </control>

basic idea is when a logo is available the text won't show and when its not, it will. I'm sure you can tailor it to your needs
