sqlite: How can results be made unique according to a column

Currently, the following sqlite query returns 45 records. I know that only 4 albums exist. How can the query be made to return only those records that are unique to albumTable.album.

Pseudo Code: where albumTable.album is UNIQUE

    query = new StringBuilder();
    query.append("select albumTable.album, artistTable.artist, songTable.filepath ");
    query.append("from albumTable ");
    query.append("inner join artistTable ");
    query.append("on albumTable.artistID = artistTable.artistID ");
    query.append("inner join songTable ");
    query.append("on albumTable.albumID = songTable.albumID ");

Thank you.
