Generally removing the cache would remove any local files that Spotify has synced, but it sounds either - a) it's created two caches, one on your internal memory and one on the SD card, or b) the library was moved over by means other than Spotify.
In the first case, you might want to try the following -
1. Open Spotify in your device
2. Go to "More", "Settings" and select "Clear saved data"
3. Close Spotify and uninstall it from your device: "Settings" » "Application" » "Manage applications" and then choose Spotify and press "Uninstall"
4. Remove these two folders from the SD card: (1) spotify2 (2) Android/data/com.spotify.mobile.android.ui
5. Install Spotify once again through the Android Market or by visiting m.spotify.com in your device's web browser
By doing this, the entire library should be removed, and allow you to start afresh. Then, when you start using the application again, you might need to set your device up to get the Spotify Cache to save directly to the SD card.
1. Open Spotify in your mobile
2. Go to “More”, “Settings” and select “Clear saved data”
3. Press More and then Log Out
4. While at the login screen, press the hardware Menu key and select SD Location
5. Enter the path to a folder on the SD card
6. Finding the exact path to your SD card can be done with a file manager, and can differ between phones.
On the Samsung Galaxy S, for example, you should use: /mnt/sdcard/external_sd
Spotify will then store tracks in this folder:/mnt/sdcard/external_sd/Android/Data/com.spotify.mobile.android.ui
In order to stop Spotify syncing your entire library, when connecting to Spotify on both your computer and Android phone the name of your phone will appear on the desktop version of Spotify. At the top, there are two boxes - Manually select which playlists to sync, or Sync all playlists. It sounds like "Sync All Playlists" might be selected, so click on the other one. You'll then be able to select which playlists you wish to sync.
