How can I get rid of ads that play music and say stuff?

Try "MalwareBytes" to start cleaning up your system:

(free version has no "real-time" shield)

Browser 'pop-up blockers' are lightweight, paper thin defenses and advertisers (legit & malware purveyors) know how to get by those very easily. Users must boost their own defenses these days.
Get Firefox as your default browser & use it for everyday surfing; fall back to iE only for "last resort" viewing of substandard websites & Windows updates.
The following tips help, but methods (vectors) constantly change.
FIREFOX: Tools> Options> Privacy> top drop menu set to "Firefox will use custom settings..."> Check 'Accept Cookies from sites'
â–ºUn-Check 'Accept 3rd Party cookies'.

My own choices (Official Mozilla) to bolster Firefox is here:

"AdBlock Plus" & "Better Privacy" also help defray rubbish.
►► At minimum, get the #1 item for malware prevention: NoScript.
[see this page for how it works, and how to use it...very simple; http://noscript.net/features#contentblocking

CHROME> wrench icon> Preferences> Under the hood> Content settings> Cookies (heading): tick "Allow local data..." & "Ignore exceptions and block 3rd party..."> close tab.
AdBlock plus available. See Add-on's for Chrome.

"NotScript" performs well also, but is a bit of a bugger to configure.

INTERNET EXPLORER does not handle 3rd party assets very well and won't give nearly the control as Firefox or Chrome: it is garbage. Use at your own risk.

And, get this installed: â–º"HOSTS file" (from mvps.org) which blocks evil webpage assets from re-directs which install malware or trashware. (Vista requires special instructions; on-page link)
