Assuming the album doesn't exist, the next step is to guide the user to correct sources. If the album doesn't exist, I should inform them and suggest checking the correct spelling. Also, if they're looking for a portable download, I should recommend using official platforms like iTunes, Bandcamp, or Spotify, advising legal downloads. Also, mention safety, avoiding pirated sites to prevent malware.

Another angle: sometimes people refer to an album by a different name due to translation or nickname. Could "Omen" here refer to another band? Or maybe "elephant eyes" is a metaphor or a title from another source. Alternatively, maybe the user heard the band and album name mentioned somewhere and got the names mixed up.

I should also consider that the user might be looking for a free version, so maybe suggest checking libraries or free legal music sites. Additionally, if the album isn't real, offer to help with similar or related albums by Omen. Maybe the user is interested in darker metal and looking for similar bands.

In summary, my response should first clarify the non-existence of the specified album, provide possible reasons for the confusion, and guide the user towards legitimate sources for music downloads, emphasizing legality and safety.

Next, the user is asking to download the album portably. So they want a portable version, maybe as an MP3 or MP4 file that can be played on various devices. But before that, I need to confirm if such an album exists. Since I can't find an album named "Elephant Eyes" by Omen, maybe the user is referring to a compilation or a side project. Alternatively, perhaps the user is confusing it with another band.
