Psychologists say you can pick up a lot of personality cues just from a guy's ringtone.
Step 1: Listen for a default ring Keep your ears open for a guy with a default ring. This is the choice of CEOs because: a) they're too busy to download the latest hit; b) they don't need to impress anyone with their taste in music; and c) they need to look professional.
TIP: Hear an action drama theme? Statistically, the guy is probably an up-and-coming young executive.
Step 2: Pinpoint the geeks If a sweet geek is what you're after, gravitate toward guys who program their phone with songs from popular movie soundtracks.
Step 3: Find an old-fashioned gent Find an old-fashioned guy with traditional values by listening for a ringtone that mimics a vintage telephone.
Step 4: Check out the classical music lovers The guy with classical tunes on his phone might have highbrow tastes… or he might just be trying to make himself look cultured, in which case he's just pretentious!
Step 5: Beware top 10 hits Beware of guys with a top 10 hit on their phone. They are trying to send the signal that they're nice, normal guys, when in fact they tend to be macho, manipulative, competitive, and self-centered.
Step 6: Popular, but not original Guys with popular rap or hip-hop ringtones are in the majority -- they might be nice, but they're not original.
TIP: If he's over 40 with rap or hip-hop music on his phone, he's truly young at heart, or trying hard to seem younger than he looks.
Step 7: Find the fun guys If you like fun-loving guys, listen for jokey tunes. Just keep in mind that their good sense of humor may come with a grating need for attention.
Step 8: Look out for playas Need we say it? Stay away from womanizers who broadcast their wayward ways with love 'em and leave 'em tunes.
FACT: AT&T's top-selling ringtone of 2007 was "Party Like a Rock Star" by Shop Boyz.
