I use music a lot in my classes, especially with Beginning English Language Learners. When I search for lyrics on the Internet to songs I want to use, I can usually find them. However, most of these sites have incessant and obnoxious pop-up ads.
There’s a new site added to that list. It’s called Lyrics Mode. It looks like they have a nice selection of lyrics — at least I was able to find ones to songs I like to use. It has the actual music to at least some, too. And it seems easy to use, with no annoying pop-ups.
