The title track incorporates more of a hip-hop attitude, but keeps those trademark harmonies intact. The protagonist apologizes for various infractions in the relationships, including "having another chick on the side." Again, such lyrics detract from the overall track. Better is "Go," a dance track that should bring people to the floor. Their deep harmonies add even more bass to the chorus, making it particularly club-friendly. "Blowin' Me Up" should also receive club play, as it has a driving beat and a catchy chorus. This song nicely merges All-4-One's doo-wop style with modern dance track conventions, emerging as the best example of the group updating their sound for a younger audience.
All-4-One finally showcases their impressive harmonizing skills on the acappella "You Don't Know Nothin'," originally a hit for '90s female group For Real. Here is where All-4-One's talent really shines, and it would behoove them to record an album comprised of all acappella tracks (with the recent success of acappella groups like Straight No Chaser, All-4-One could really find their niche here).
No Regrets may fare best in clubs, where the dance tracks could find some success. On future albums, All-4-One should focus on better distinguishing themselves from other pop groups. Their harmonies are their greatest strength, and genres such as doo wop, 70s soul, and acappella would best utilize that talent. Better songwriting would also help, as would merging their harmonies with modern dance beats ("Blowin' Me Up" being the model). All-4-One's voices remain refreshingly unchanged, and they should record material that best suits their vocal skills—and sets them apart from the crowd.
