is there a hidden meaning to それとなく?


I got bumped in the term それとなく in these two sentences

[code]

    1. だから今はそれとなく散々淡々と暮らしていて
    2. 思い出して魚の眼 Oh Oh! それとなくキルミーして！Oh Oh!
    
[/code]

Jisho said `indirectly; obliquely`, but feels like it is not fit well to the
translation. There is any nuance or other meaning to this?

disclaimer, these two lines are from the song `ガランド`. So probably they are not
100% understandable or grammatical correct. But any example that will help me
understand this term better will be great :-)

Thanks, Or
