In recent years the music-sharing sites have exploded. It is not necessary to use P2P programs or similar programs, so you can listen or musica gratis en internet online. We can also do so directly. If you want to know a good list of sites where you can listen to your favorite songs without wasting time, and then make sure you read this list (The first four of the top are a favorite): 

7.  BeeMP3 

We started with BeeMP3 ranking. As mentioned before, I think the simplest of all. It offers a browser that does not play all mp3 streaming, but in return provides detailed information on the results. Its weakness is that not host the mp3 on their servers, so there are chances that your results may return non-existent files. 

6. The Hype Machine 

Is an aggregator MP3 that tracks the files of a vast legion of blogs dedicated to music. If one looks for the file name, you can get a long list of results, which can be heard in the same list. In addition, The Hype Machine offers a variety of tools, how to create playlist with your favorite songs and download free music from the site 

5. SkreemR 

SkreemR is one of the most simple mp3 search engines I've found, can play any song, but unlike The Hype Machine does not allow direct downloading of songs. 

4. SeeqPod 

SeeqPod should be among the most popular MP3 search engine on the Internet. Is very simple to use, also has a trick to download free music hosting. SeeqPod enables us to navigate through the results and play the tracks in a flash player. 

3.  Deezer 

Deezer is the best-designed search engine I've seen, hosts its own mp3, have a Spanish interface. But also, as they mention it, have a system that learns from our tastes, called Smart Radio 

2.  Goear 

Their search often becomes slow or overloaded, is one of the sites with more music in Spanish. Until a few days, my favorite site for music. 

1.  Mp3tube

But these days, I've become accustomed of Mp3tube. A 2.0 portal with a vast number of users, and many more audios. I searched everywhere topics, some a little far-fetched, and in most cases I found. But what I liked most is the fact of hosting your own MP3s and play them at a good speed. 
 
While we have made a small top, with MP3tube taking palms, there are many search engines, which we have discussed here.
