How Can I Increase My Number Of Allowed Downloads Into My Tablet?? I Need 2,000

I have Spotify Premium (and have had for more than a year now). I use 3 tablets (2 ASUS ZEN Pads and a Samsung). I just bought a 128 GB SDXC SanDisk Class10 Ultra memory card for my new ASUS Zen Pad 8.0.....I need to be able to download (for offline use) abut 2,000 or 3,000 more of my tracks that are already listed now in my Playlists ...to get them "physically into my tablet"....so I can access al of my most important tracks while I ma "offline"...I am willing to pay extra money for this!
