The recording took place just after the success of singles like "I Can't Explain" and "My Generation". The band itself later acknowledged that they felt it was a rushed job, and that it didn't fully reflect the intensity of their live performances. Although it didn't reach the sales of their later works, peaking at number 5 on the UK charts, over time critics have re-evaluated it as a fundamental rock album. Its hard sound, uncommon for that time, and how it anticipated styles like punk and heavy metal are highlighted. In fact, in 2008 it was included in the National Recording Registry, being the first recording by The Who to receive that recognition.
Several songs from My Generation had their own life as singles. "My Generation", which was released before the album, reached number 2 in the UK. "A Legal Matter", "La-La-La Lies", and "The Kids Are Alright" were also released. The latter did not have the same commercial impact, partly because the band was already working with a new label. However, "The Kids Are Alright" was a success in Sweden, reaching number 8. Both "My Generation" and "The Kids Are Alright" have become widely covered songs by other artists. While "My Generation" is a direct and aggressive track, a precursor to movements like punk and heavy metal, "The Kids Are Alright" shows a more melodic facet, with resonant guitars and vocal harmonies, but without losing the band's characteristic energetic rhythm. The album is also considered an important antecedent of the "power pop" genre.
