“And I said baby … it’s 3 a.m., I must be lonely.” If you were anywhere within earshot of a radio or MTV in the mid-to-late 1990s, that little slice of earworm was no doubt getting stuck in your head. The culprits? Rob Thomas and his band mates in Matchbox Twenty, whose debut album, “Yourself or Someone Like You,” took pop radio by storm. Hits like the aforementioned “3AM,” “Push,” “Real World” and more pushed the sales of this album upwards of MILLIONS of copies. (It sold just over 600 copies in its first week; today, it has sold more than 15 million.) And while the songs (and the band) may get dissed nowadays for being too vanilla, you can’t deny the pop sensibilities  of  Thomas, who not only as a golden voice, but also a golden ear for hit-making music. (As we would, unfortunately, find out when he gets introduced to one Carlos Santana.) Is “Yourself” a classic album? Depends on your definition of “classic.” But you can’t deny that many of these songs are just so damn catchy. And isn’t that sometimes good enough?
