To provide the solution for those who have given up, without spoiling it for those still trying, a fun technique is to set the font colour of the answer to white. This makes it invisible until it is highlighted by moving the cursor across while holding the left click down (as if selecting for copy).

The long characters of ABBA's song is too obvious.
The last thing I would want to hear about a band's reissue campaign is somebody trying to remaster at the highest peak known to mankind.
^^ The idea behind ABBAgrams though, is not so much that they are difficult to solve, but that they are difficult to devise. The anagram itself should have some vaguely plausible ABBA connotation, rather than just being a nonsense sentence.
Hang on, I'll come up with a new one as an example..
(I like the non-English angle though, it opens up more opportunities)
