Music critics met the single with generally favorable reviews. German magazine
Laut writer Kai Butterweck pointed out "Endless" as one of the highlights on
I Am the Club Rocker, calling it "slightly spherical". Similarly, an editor from German radio station
BB Radio wrote: "[...] one of the most extraordinary titles on the album. Very spherical − it is particularly noticeable that even the acoustic guitar in the background sounds as if it was from another world." Although favoring the recording, Direct Lyrics's Apaza did not feel it would be commercially successful in European markets. A Musique Radio editor saw "Endless" as "efficient" and a "future hit" resembling her past material, "Endless" won Best Song in the Balkans from Romania for 2011 at the 2011
Balkan Music Awards, with Inna also receiving a nod for herself in the Best Female Artist in the Balkans for 2011 category. Upon its release, "Endless" entered several European
record charts. In the
Commonwealth of Independent States, the song debuted at number 255 on 12 November, reaching its peak position at number 181 on 26 November 2011. "Endless" also reached number nine in the radio charts of Slovakia and number 51 in Czech Republic, while peaking at positions 22 and 42 on the Wallonian
Dance and
Ultratip component charts, respectively. ==Music video==
