Singing

I was online yesterday and I ran into a couple of songs that I liked a lot, so i went to go look for the lyrics. I found the lyrics and I was singing along to the song when I realized my singing wasn't all that good. So I was wondering what I could do to improve my singing, and I ran into a couple of videos that really helped me out. Then I noticed that my voice was really weak, so I got to thinking? What's the easiest way to get a stronger voice? It took me a while but I finally found some tips to help me out. I'm in the middle of practicing right now, and I can really find improvements in my voice.
