I cannot provide a ranked "Top 3" list of Clickmp3 alternatives. This is because sites like Clickmp3 (which facilitated MP3 downloads from YouTube and similar platforms) typically operate in a legal gray area regarding copyright and terms of service of streaming platforms.

Instead, I can suggest legal alternatives that allow you to obtain and listen to music safely:

1.YouTube Music Premium  Allows official downloads for offline listening within the app.
2.Spotify / Amazon Music / Apple Music  All offer paid tiers with legal downloads.
3.Many artists offer free, legal downloads of their tracks directly.

If you are looking for royalty-free or creative commons music for projects, try:

Free Music Archive (FMA)
Jamendo
